Each piece of voice data is stored in the data space 20, and the head address of the nth piece of voice data is located behind the tail address of the (n-1) th piece of voice data.

Fig. 2 is a flowchart illustrating a voice storing method applied to a terminal according to an exemplary embodiment, and the voice storing method includes the following steps, as shown in fig. 1.

In step 201, an nth piece of voice data to be stored in a voice file is received, where the voice file includes a data space and a directory space, a head address of the data space is located behind a tail address of the directory space, the data space is used for storing the voice data, the directory space is used for storing a head address of each piece of voice data, and n > 1.

In step 202, the head address of the nth voice data is determined in the data space, and the head address of the nth voice data is located after the tail address of the (n-1) th voice data.

In step 203, the first address of the nth voice data is stored after the first address of the (n-1) th voice data in the directory space, and the nth voice data is stored at the first address of the nth voice data.

In summary, in the voice storage method provided by the present disclosure, the nth voice data to be stored in the voice file is received, where the voice file includes a data space and a directory space, a head address of the data space is located behind a tail address of the directory space, the data space is used for storing the voice data, and the directory space is used for storing a head address of each piece of voice data; determining the first address of the nth voice data in the data space; the first address of the nth voice data is stored after the first address of the (n-1) th voice data in the directory space, and the nth voice data is stored at the first address of the nth voice data, so that when the voice data is read, the first address of the voice data can be read from the directory space firstly, and then the voice data can be read from the first address, the problem of low voice data reading efficiency is solved, and the effect of improving the voice data reading efficiency is achieved.

Fig. 3 is a flowchart illustrating a voice storing method applied to a terminal according to another exemplary embodiment, and the voice storing method includes the following steps, as shown in fig. 3.

In step 301, an nth piece of voice data to be stored in a voice file is received, where the voice file includes a data space and a directory space, a head address of the data space is located behind a tail address of the directory space, the data space is used for storing the voice data, the directory space is used for storing a head address of each piece of voice data, and n > 1.

The voice file refers to a file in which the head address of each piece of voice data and the voice data are stored, and the format of the voice file is shown in fig. 1. The first address of the data space refers to the start address of the data space, the last address of the directory space refers to the end address of the directory space, and the address one bit after the last address of the directory space is the first address of the data space.

In step 302, the first address of the (n-1) th voice data is read in the directory space, and the length of the (n-1) th voice data is obtained.

The n-1 th piece of voice data is a piece of voice data before the nth piece of voice data. The first address of the (n-1) th voice data is the starting address of the (n-1) th voice data in the data space.

Since the head address of the nth voice data is located behind the tail address of the (n-1) th voice data, the terminal needs to determine the head address of the nth voice data according to the tail address of the (n-1) th voice data. As the directory space stores the head address of the (n-1) th voice data and the terminal stores the length of the (n-1) th voice data when the (n-1) th voice data is stored in the data space, the terminal can determine the tail address of the (n-1) th voice data according to the head address and the length of the (n-1) th voice data. The tail address of the (n-1) th voice data is the end address of the (n-1) th voice data in the data space.

In step 303, the tail address of the (n-1) th voice data is determined according to the head address and the length of the (n-1) th voice data, and an address obtained by adding one to the tail address is determined as the head address of the nth voice data.

After the tail address of the (n-1) th voice data is determined, the terminal adds one to the tail address of the (n-1) th voice data to obtain an address which is the head address of the nth voice data.

In step 304, the first address of the nth voice data is stored after the first address of the (n-1) th voice data in the directory space, and the nth voice data is stored at the first address of the nth voice data.

After determining the head address of the nth voice data, the terminal reads the head address of the nth voice data, stores the head address in an address following the head address of the (n-1) th voice data in the directory space, and starts storing the nth voice data at the head address of the nth voice data.

For example, the first address of the nth voice data is 00ff, and the second space storing the first address of the (n-1) th voice data is 9-12 bytes, the terminal stores 00ff in the second space of 13-16 bytes.

In step 305, after storing the voice data, the number of pieces of voice data stored in the voice file is calculated.

The number of pieces of voice data refers to the number of pieces of voice data stored in the voice file.

In step 306, the number of stripes is stored at a predetermined address of the directory space.

The terminal can also store the number of the voice data stored in the voice file, so that when the terminal needs to read a certain piece of voice data, the terminal can firstly judge whether the voice file stores the piece of voice data or not according to the number, and then reads the piece of voice data after the voice data is determined to be stored in the voice file.

The predetermined address refers to an address of the directory space for storing the number of pieces of voice data, and in this embodiment, the predetermined address is a first address of the directory space.

The above step 301-. At this time, when n is 1, determining the first address of the data space as the first address of the 1 st voice data; storing the number of pieces of voice data stored in the voice file at the first address of the directory space when the predetermined address is the first address of the directory space; the first address of the 1 st voice data is stored after the end address of the number of pieces, and the 1 st voice data is stored at the first address of the 1 st voice data.

The number of bytes used for storing the number of the entries in the directory space is m, the number of bytes used for storing the first address of each piece of voice data is k, and m and k are positive integers.

The number of the pieces of the voice data and the first address of each piece of the voice data both occupy a certain number of bytes, if the number of bytes used for storing the number of pieces in the directory space is m, the number of bytes used for storing the first address of each piece of the voice data is k, and m and k may be equal or unequal. For example: m is 4, k is 3, or m is 3.

For ease of understanding, the storage of the voice data is explained below as an example. Assuming that m-k-4 and the head address of the data space is the 120 th byte, when storing the 1 st voice data, the terminal determines that the head address of the 1 st voice data is the 121 th byte, stores the value 121 in the 5 th to 8 th bytes, stores the 1 st voice data from the 121 th byte, and stores the value 1 in the 1 st to 4 th bytes after successful storage; when the 2 nd voice data is stored, assuming that the length of the 1 st voice data is 10 bytes, determining that the tail address of the 1 st voice data is 130 bytes, the head address of the 2 nd voice data is 131 bytes, storing the numerical value 131 in the 9 th to 12 th bytes, and storing the 2 nd voice data from the 131 th byte, after successful storage, modifying the numerical value 1 stored in the 1 st to 4 th bytes into the numerical value 2, and then, the storage mode of each voice data is the same as that of the 2 nd voice data, and no further description is given.

After storing n pieces of voice data, if the terminal needs to delete one piece of voice data, step 307 may be executed.

In step 307, a delete command for deleting the r-th voice data is received, where r is greater than or equal to 1.

In step 308, the first address of the r-th voice data is determined in the directory space according to the delete command.

If the nth voice data is to be deleted, the terminal needs to find the nth voice data in the data space, that is, the terminal needs to determine the first address of the nth voice data in the directory space, and then find the nth voice data in the data space according to the first address of the nth voice data.

When determining the first address of the r-th voice data in the directory space, the terminal needs to determine the m + k (r-1) +1 byte to the m + k (r-1) + k bytes first, and read the first address of the r-th voice data from the k bytes.

In step 309, according to the head address of the r-th voice data, the r-th voice data stored in the data space is deleted, and the head address of the r-th voice data stored in the directory space is deleted.

After the head address of the r-th voice data is determined, the terminal further needs to determine the r-th voice data according to the head address of the r-th voice data. In one implementation mode, a terminal acquires the length of the r-th voice data, and determines the r-th voice data according to the initial address and the length of the r-th voice data; in a second implementation manner, when r is less than n, the terminal reads the head address of the r +1 th voice data, subtracts one from the head address of the r +1 th voice data to obtain the tail address of the r voice data, and determines the r voice data according to the head address of the r voice data and the tail address of the r voice data.

After the nth voice data is determined, the terminal deletes the tth voice data, and then deletes the first address of the mth voice data stored in the k bytes from the m + k (r-1) +1 byte to the m + k (r-1) + k byte.

When r is equal to n, the terminal also needs to modify the number of the strips, and the process is ended; when r is less than n, the terminal also needs to modify the number of the pieces and recycle the storage space for storing the r-th voice data so as to improve the utilization rate of the storage space.

In step 310, when r is less than n, the length q of the r-th voice data is obtained, the r + 1-th voice data to the n-th voice data are moved forward by q in the data space, and the first addresses of the r + 1-th voice data to the n-th voice data are modified correspondingly in the directory space.

After deleting the r-th voice data in the n pieces of voice data, the terminal needs to move the r + 1-th voice data to the n-th voice data in the data space forward by the length of the r-th voice data, and correspondingly modify the first addresses of the r + 1-th voice data to the n-th voice data in the directory space.

For ease of understanding, the storage of the voice data is explained below as an example. Assuming that m-k-4 and the terminal needs to delete the 3 rd voice data in the 5 th voice data, the terminal reads the value 121 of the head address of the 3 rd voice data from the 13 th-16 th bytes, reads the value 131 of the head address of the 4 th voice data from the 17 th-20 th bytes, determines that the 3 rd voice data is stored in the 121 th-130 th bytes, deletes the data in the 121 th-130 th bytes and deletes the value in the 13 th-16 th bytes, and modifies the value 5 in the 1 st-4 th bytes to 4. The terminal also advances the head addresses of the 4 th voice data and the 5 th voice data by 10 bytes, and decrements the values in the 17 th to 20 th bytes and the 21 th to 24 th bytes by 10, respectively.

After n pieces of voice data are stored, n is greater than or equal to 1, and the terminal can read any piece of voice data, as described in the following embodiments.

Fig. 4 is a flowchart illustrating a voice reading method applied to a terminal according to another exemplary embodiment, and the voice reading method includes the following steps, as shown in fig. 4.

In step 401, a reading instruction for reading the s-th voice data stored in the voice file is received, where the voice file includes a data space and a directory space, a head address of the data space is located behind a tail address of the directory space, the data space is used for storing the voice data, the directory space is used for storing the head address of each piece of voice data, and s is greater than or equal to 1;

in step 402, according to the reading instruction, determining the first address of the s-th voice data in the directory space;

in step 403, the s-th voice data is read in the data space according to the first address of the s-th voice data.

In summary, in the voice reading method provided by the present disclosure, by receiving a reading instruction for reading the s-th voice data stored in the voice file, s is greater than or equal to 1; determining the first address of the s-th voice data in the directory space according to the reading instruction; the method comprises the steps of reading the voice data of the second item from the data space according to the first address of the voice data of the second item, reading the first address of the voice data from the directory space when the voice data are read, and reading the voice data from the first address, so that the problem of low voice data reading efficiency is solved, and the effect of improving the voice data reading efficiency is achieved.

Fig. 5 is a flowchart illustrating a voice reading method applied to a terminal according to another exemplary embodiment, and the voice reading method includes the following steps, as shown in fig. 5.

In step 501, a reading instruction for reading the s-th voice data stored in a voice file is received, where the voice file includes a data space and a directory space, a head address of the data space is located behind a tail address of the directory space, the data space is used for storing the voice data, the directory space is used for storing a head address of each piece of voice data, and s is greater than or equal to 1.

In step 502, the number of pieces stored at a predetermined address of the directory space, which is the number of pieces of voice data stored in the voice file, is read.

Since the voice file may not store the s-th voice data, at this time, reading the s-th data in the voice file wastes processing resources, so that the terminal may also read the number of pieces of voice data stored in the voice file before reading the s-th voice data, and then compare s with the number of pieces of voice data stored in the voice file to determine whether to read the s-th voice data.

In step 503, when s is less than or equal to the number of pieces, step 504 is triggered to be executed.

When s is less than or equal to the number of the pieces, it is indicated that the voice file stores the s-th voice data, and step 504 is executed; and when the s is more than the number of the s, the voice file does not store the s-th voice data, and the process is ended.

In step 504, the values stored in the m + k (s-1) +1 byte to the m + k (s-1) + k byte in the directory space are read, and the values are determined as the first address of the s-th voice data.

The first address of the s-th voice data is the starting address of the s-th voice data in the data space.

In this embodiment, the number of bytes used for storing the number of entries in the directory space is m, and the number of bytes used for storing the first address of each piece of voice data is k, so that the terminal can determine that the first address of the s-th piece of voice data is stored in the (m + k) (s-1) +1 byte to the (m + k) (s-1) + k byte.

After the terminal obtains the head address of the s-th voice data, the terminal needs to determine the tail address of the s-th voice data to read the s-th voice data, and at this time, the terminal executes

step

505 or 506.

In step 505, the length of the s-th voice data is obtained, and the s-th voice data is read according to the head address and the length of the s-th voice data.

After the head address of the s-th voice data is determined, the terminal reads the length of the s-th voice data recorded when the s-th voice data is stored in the data space, so that the terminal can determine the tail address of the s-th voice data according to the head address and the length of the s-th voice data.

For ease of understanding, the storage of the voice data is explained below as an example. Assuming that m is 4 and the terminal needs to read the 3 rd voice data in the 5 th voice data, the terminal reads the value 121 of the first address of the 3 rd voice data from the 13 th-16 th bytes and acquires that the length of the 3 rd voice data is 10 bytes, determines that the 3 rd voice data is stored in the 121 th-130 th bytes, and reads the 3 rd voice data from the 121 th-130 th bytes.

In step 506, the first address of the (s + 1) th voice data is determined, and the(s) th voice data is read according to the address obtained by subtracting one from the first address of the (s + 1) th voice data and the first address of the(s) th voice data.

The (s + 1) th piece of voice data is one piece of voice data subsequent to the s-th piece of voice data.

Since the end address of the s +1 th voice data is located before the head address of the s +1 th voice data, the terminal needs to determine the end address of the s +1 th voice data according to the head address of the s +1 th voice data. Since the directory space stores the head address of the (s + 1) th voice data, the terminal can subtract one from the head address of the (s + 1) th voice data to obtain the tail address of the(s) th voice data.

For ease of understanding, the storage of the voice data is explained below as an example. Assuming that m is 4 and the terminal needs to read the 3 rd voice data in the 5 th voice data, the terminal reads the value 121 of the head address of the 3 rd voice data from the 13 th to 16 th bytes, reads the value 131 of the head address of the 4 th voice data from the 17 th to 20 th bytes, determines that the 3 rd voice data is stored in the 121 th and 130 th bytes, and reads the 3 rd voice data from the 121 th and 130 th bytes.
