2. Audio bit depth - Wikipedia

   en.wikipedia.org/wiki/Audio_bit_depth

   Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.

4. Sound Recorder (Windows) - Wikipedia

   en.wikipedia.org/wiki/Sound_Recorder_(Windows)

   Before Windows 7, Sound Recorder could save the recorded audio in waveform audio (.wav) container files.Sound Recorder could also open and play existing .wav files. To successfully open compressed .wav files in Sound Recorder, the audio codec used by the file must be installed in the Audio Compression Manager (ACM); Windows installations dating back to at least Windows 95 came with a selection ...

6. WAV - Wikipedia

   en.wikipedia.org/wiki/WAV

   The WAV format is limited to files that are less than 4 GiB, because of its use of a 32-bit unsigned integer to record the file size in the header. Although this is equivalent to about 6.8 hours of CD-quality audio at 44.1 kHz, 16-bit stereo, it is sometimes necessary to exceed this limit, especially when greater sampling rates , bit ...

7. High-resolution audio - Wikipedia

   en.wikipedia.org/wiki/High-resolution_audio

   High-resolution audio. High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD Audio.
