MF_MT_AUDIO_BITS_PER_SAMPLE attribute (Mfapi.h) - …

    https://docs.microsoft.com/en-us/windows/win32/medfound/mf-mt-audio-bits-per-sample-attribute
    If some bits contain padding, set the MF_MT_AUDIO_VALID_BITS_PER_SAMPLE attribute to specify the number of bits of valid audio data in each sample. If the audio contains 8 bits per sample, the audio samples are unsigned values. (Each audio sample has the range 0–255.) If the audio contains 16 bits per sample or higher, the audio samples are signed …
