The present application discloses a recording method, device, system, and medium. The method includes: separately obtaining the recording parameters and the frequency of the clock signal contained in the audio data, and saving the frequency of the clock signal and the frequency of the clock signal after obtaining the number of the clock signal within the specified area of the recording file. Since the frequency of the clock signal and the number of clock signals are obtained, in the case of playing the recording, the duration of the recording file can be calculated by the ratio of the number of clock signals in the file header field to the frequency of the clock signal. Since the clock is calculated in advance The number of signals makes it unnecessary to calculate the number of clock signals when playing the recording, so the calculation time is short. In addition, because only two data are needed to calculate the length of the recording file, the calculation method has a small workload and the calculation method is simple, so it speeds up the file. The speed of startup. In addition, a recording device, system, and medium provided by the present application correspond to the above-mentioned recording method, and the effect is the same as above.
Description
technical field [0001] The present application relates to the technical field of voice storage, in particular to a recording method, device, system and medium. Background technique [0002] With the development of science and technology and economy, people pay more and more attention to the sense of satisfaction brought by the spiritual world, and enjoy the pleasure brought by music and movies more and more. Therefore, the quality of recording is more and more valued by people. [0003] The existing recording format is mainly the lossless audio format (Waveform Audio File Format, WAV). WAV adopts the resource interchange file standard (Resource Interchange File Format) file format structure. The WAV file header field generally consists of RIFF chunk (RIFF chunk), format chunk (Format chunk) and data chunk (Data chunk). The format chunk includes the sampling rate, number of channels, sampling depth, etc. The data chunk includes the size of the recorded data. When the signal t...
