Audio sample rates on DV tape - vegascreativesoftware.info
https://www.vegascreativesoftware.info/us/forum/audio-sample-rates-on-dv-tape--38975/
The DV standard is for 32KHz audio to be sampled with 12 bits resolution, but what I think is happening is that when this is saved on the hard disk (either as AVI or WAV file), an addiitonal 4 bits of padding is added so that the data is stored in 16 bit words. This would be much easier for most applications to work with.

The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.

DV video information is carried in a nominal 25 megabit per second (Mbits/sec) data stream. Once you add in audio, subcode (including timecode), Insert and Track Information (ITI), and error correction, the total data stream comes to about 29 Mbits/sec or 3.6 MBytes/sec. Roger Jennings' papers run through the detailed numbers.

The maximum permissible total bit rate is 9.6 Megabits per second. Channel/resolution combinations that would exceed this need to be compressed. In uncompressed modes, it is possible to get up to 96/16 or 48/24 in 5.1, and 192/24 in stereo. To store 5.1 tracks in 88.2/20, 88.2/24, 96/20 or 96/24 MLP encoding is mandatory.

48 kHz, 96 kHz, and 192 kHz are recommended for digital formats, DVDs, and audio to be used in a video. 48 kHz is the standard sample rate for these formats. What Bit Depth Should You Use for Your Audio? Besides the sample rate, you also need to consider the bit depth for your audio. A higher bit depth offers more dynamic range.

Nyquist’s Theorem. According to Nyquist’s Theorem, for an accurate digital representation of a sound wave, the sample rate must be, at least, two times bigger than the highest frequency going to be recorded.As the highest sound a human can hear has a frequency of 20 kHz, the minimum sample rate must be 40 kHz to be possible to digitalize this frequency.

In addition, the DV specification also supports 16-bit audio at 44.1 kHz (706 kbit/s per channel, 1.4 Mbit/s stereo), the same sampling rate used for CD audio. In practice, the 48 kHz stereo mode is used almost exclusively. Digital Interface Format
