PCM data size for audio encoding - Intel Communities

Yes, you are right, size of AAC audio frame is equal to 1024 samples per channel (2048 bytes), size of MP3 frame - 1152 samples per channel (2304 bytes). It means that every call GetFrame of encoder encodes exactly frame_size * num_channels samples of input data. This size doesn't depend on sample frequency.
FFmpeg - confused with the concept of audio frame size …

In FFmpeg, audio frame size refers to samples, not bytes. So one audio frame of a 16-bit 4-channel PCM stream will have 1024 x 16 x 4 = 65536 bits = 8192 bytes.

Raw stream may contains PCM or DSD audio data, that compressed or not. The audio data is splitted to portions (frames). Each frame (group of frames) have a header. As rule, the meta-information contains in the header. Is PCM audio better? PCM audio one of audio formats. In TV applications it's considered as a lossless one. So, PCM provides ...

The default signal compression encoding in a DS0 signal is either Ley PCM audio (in North America and Japan) or Ley A PCM audio (In Europe and most of the rest of the world). These are logarithmic compression systems in which a number of linear 12 or 13-bit PCM audio samples are assigned a value of 8 bits.
