其中，步骤103使用HiFi播放功能，是指使用HiFi芯片解码输出高质量音频。Wherein, step 103 uses the HiFi playback function, which refers to decoding high-quality audio using a HiFi chip.
步骤101中要获取的当前播放条件，包括：The current playing conditions to be obtained in step 101 include:
当前选定的音频输出设备是否支持HiFi播放和要播放的音源文件是否符合HiFi播放的音质要求。Whether the currently selected audio output device supports HiFi playback and whether the audio file to be played matches the sound quality requirements of HiFi playback.

当所述当前选定的音频输出设备不支持HiFi播放时，判定为不符合HiFi播放功能要求；When the currently selected audio output device does not support HiFi playback, it is determined that the HiFi playback function requirement is not met;
当所述音源文件的音质不符合HiFi播放的音质要求，判定为不符合HiFi播放功能要求；When the sound quality of the sound source file does not meet the sound quality requirement of HiFi playback, it is determined that the HiFi playback function requirement is not met;
当所述当前选定的音频输出设备支持HiFi播放，且所述音源文件的音质符合HiFi播放的音质要求时，判定为符合HiFi播放功能要求。When the currently selected audio output device supports HiFi playback, and the sound quality of the audio source file meets the sound quality requirements of HiFi playback, it is determined that the HiFi playback function requirement is met.
其中，判断当前选定的音频输出设备是否支持HiFi播放，包括：Wherein, determining whether the currently selected audio output device supports HiFi playback, including:
获取所选定的音频输出设备的硬件参数，根据硬件参数确定是否支持HiFi播放；例如，当所选定的音频输出设备为终端集成的喇叭时，可以通过终端获取喇叭的硬件型号，判断该型号是否在预设的支持HiFi的硬件型号列表中，或者获取喇叭的表征是否支持HiFi播放的属性值，当该属性值表示支持时，则确定该喇叭支持HiFi播放。其中，标准喇叭是否支持HiFi播放的属性，可以从设备寄存器中读取，也可以通过设备管脚连接方式确定。Obtain the hardware parameters of the selected audio output device, and determine whether to support HiFi playback according to the hardware parameters; for example, when the selected audio output device is a terminal integrated speaker, the hardware model of the speaker can be obtained through the terminal to determine whether the model is In the preset list of hardware models supporting HiFi, or obtain the attribute value of the speaker to support HiFi playback, when the attribute value indicates support, it is determined that the speaker supports HiFi playback. Among them, whether the standard speaker supports the HiFi playback property can be read from the device register or determined by the device pin connection mode.
当所选定的音频输出设备为耳机或外接音响设备时，也可通过如上方式获取设备的硬件参数，根据该参数确定是否支持HiFi播放。When the selected audio output device is a headset or an external audio device, the hardware parameters of the device can also be obtained by the above method, and whether HiFi playback is supported according to the parameter is determined.
或者，结合当前主流终端设备中集成的喇叭普遍无法达到HiFi播放效果的情况，简化判断流程为：Or, in combination with the speakers integrated in the current mainstream terminal devices, the HiFi playback effect is generally not achieved, and the simplified judgment process is:
当选定的音频输出设备为终端集成的喇叭时，确定该音频输出设备不支持HiFi播放；When the selected audio output device is a terminal integrated speaker, it is determined that the audio output device does not support HiFi playback;
或者，结合主流外接耳机或音响设备普通能够达到HiFi播放效果的情 况，简化判断流程为：Or, in combination with mainstream external headphones or audio equipment, you can achieve HiFi playback. The simplified judgment process is:
当选定的音频输出设备为外接的耳机或音响设备时，则确定该设备支持HiFi播放。When the selected audio output device is an external earphone or audio device, it is determined that the device supports HiFi playback.
判断要播放的音源文件是否符合HiFi播放的音质要求，表示通过检测音源文件的一个或多个属性，判定音源文件的音质，当音源文件音质好时，使用HiFi播放功能才有实际意义，用户才能听到高保真的播放效果，当音源文件本身音质不好时，即使使用HiFi播放，由于音源文件的限制，用户也无法听到高保真的播放效果，这时，则无需使用HiFi播放功能，使用普通播放。Determining whether the sound source file to be played meets the sound quality requirement of HiFi playback means that the sound quality of the sound source file is determined by detecting one or more attributes of the sound source file. When the sound quality of the sound source file is good, the HiFi playback function has practical meaning, and the user can When you hear high-fidelity playback, when the sound quality of the audio file itself is not good, even if you use HiFi playback, the user cannot hear the high-fidelity playback due to the limitation of the audio file. In this case, you do not need to use the HiFi playback function. Normal play.
包括：include:
将所述音源文件的以下属性中的至少一个与设定的相应标准进行比较后确定是否符合HiFi播放的音质要求；Comparing at least one of the following attributes of the sound source file with the set corresponding standard to determine whether the sound quality requirement of HiFi playback is met;
所述属性包括：采样精度、采样频率和位速。The attributes include: sampling accuracy, sampling frequency, and bit rate.
其中，采样精度决定了记录声音的动态范围，也称为采样位数，它以位(Bit)为单位，如8bit，16bit；8bit可以把声波分为256级，16位可以把声波分为65536级的信号，位数越高，声音的保真度越高；Among them, the sampling accuracy determines the dynamic range of the recorded sound, also known as the number of samples, which is in bits (such as 8bit, 16bit; 8bit can divide the sound wave into 256 levels, 16 bits can divide the sound wave into 65536 Level signal, the higher the number of bits, the higher the fidelity of the sound;
采样频率，称为采样速度或采样率，定义了每秒从连续的信号中提取并组成离散信号的采样个数，用赫兹(Hz)来表示。通俗的讲采样频率是指计算机每秒采集多少个声音样本，是衡量音源文件的质量标准，采样频率越高声音的还原就越真实自然，声音的保真度就越高；The sampling frequency, called the sampling rate or sampling rate, defines the number of samples extracted from a continuous signal and composed of discrete signals per second, expressed in Hertz (Hz). The popular sampling frequency refers to how many sound samples are collected by the computer every second. It is a measure of the quality standard of the sound source file. The higher the sampling frequency, the more realistic the sound is, and the higher the fidelity of the sound.
位速，是指在一个数据流中每秒中能通过的信息量，如音频文件用“128–Kbps MP3”或“64–Kbps WMA”进行描述的情形。Kbps表示“每秒千字节数”，因此数值越大表示数据越多，信息量越大，音质就越好。Bit rate refers to the amount of information that can be passed per second in a data stream, such as when an audio file is described by "128-Kbps MP3" or "64-Kbps WMA." Kbps means "kilobytes per second", so the larger the value, the more data, the larger the amount of information, the better the sound quality.
对该判定过程举例说明如下：An example of this decision process is as follows:
以采样精度为标准，判断音源文件音质，预设标准为：采样精度等于1bit或大于等于20bit，表示采样精度等于1bit，或者采样精度大于等于20bit的音源文件符合HiFi播放的音质要求；例如，DSD(Direct Stream Digital，直接比特流数字)格式的音源文件，其采样精度等于1bit，是一种成熟的高 音质音源文件。The sound quality of the sound source file is judged by the sampling precision as the standard.

The preset standard is: sampling accuracy is greater than or equal to 16 bits, sampling frequency is greater than or equal to 44.1 kHz, and bit velocity is greater than or equal to 1000 kbps. That is, at least two of the three attributes are greater than or equal to the set threshold, indicating that the sound source file with the sampling precision greater than or equal to 16 bits and the sampling frequency greater than or equal to 44.1 kHz meets the sound quality requirements of HiFi playback; or, the sampling precision is greater than or equal to 16 bits and the bit A sound source file with a speed greater than or equal to 1000 kbps meets the sound quality requirements of HiFi playback; or a sound source file with a sampling frequency greater than or equal to 44.1 kHz and a bit rate greater than or equal to 1000 kbps meets the sound quality requirements of HiFi playback; or, the sampling accuracy is greater than or equal to 16 bits and the sampling frequency is greater than or equal to A sound source file with a 44.1 kHz and a bit rate greater than or equal to 1000 kbps meets the sound quality requirements of HiFi playback.
或者，以采样精度、采样频率和位速为标准，判断音源文件音质，预设标准为：采样精度等于1bit的音源文件符合HiFi播放的音质要求；采样精度不等于1bit时，采样精度大于等于16bit，采样频率大于等于44.1kHz和位速大于等于1000kbps这三个条件中至少满足两个(即表示三个属性中至少有两项大于等于设定阈值)，表示当采样精度大于等于16bit且采样频率大于等于44.1kHz的音源文件符合HiFi播放的音质要求；或者，采样精度大于等于16bit且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求；或者，采样频率大于等于44.1kHz且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求；或者，采样精度大于等于16bit且采样频率大于等于44.1kHz且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求。Or, based on the sampling accuracy, sampling frequency and bit rate as the standard, determine the sound quality of the sound source file.
