Recently studied how to draw a WAV waveform on iOS. Looked up a lot of information, did not find a very complete introduction, I here to summarize some experience.First of all, we need to understand the 3 important indicators of WAV: sample rate, number of sample bits, number of channels. The following is illustrated in the example of 16KHz, 16Bit, Mono.Sample rate: (also known as sampling speed or sampling

I recently added Vivo to try those songs in the natural environment. Unfortunately, Vivo won't be able to play those ALAC. What makes people laugh most

This design idea: first open a normal WAV audio file, from the 44 bytes in front of the defined file header, remove the file header definition message, placed in a file header structure. Then open the ALSA audio driver, from the file header structure to remove the sampling accuracy, the number of channels, sampling frequency three important parameters, using the ALSA audio-driven API set parameters, finally open the
