Audio Sample-Rate Conversion

The conversion from an audio signal sampled at 44.1 kHz (CD quality) to an audio signal sampled at 96 kHz (DVD quality) can be done in two steps. Before describing the two steps, an audio file reader is created to provide the input audio signal. In this example an OGG file is used, but it can replaced with any (MP3, FLAC, WAV, M4A) audio file as long as it is sampled at 44.1 kHz.
Why 44.1 kHz? | Intelligent sound engineering

44.1 kHz, or 44,100 samples persecond, is perhaps the most popular sample rate used in digital audio, especially for music content. The short answer as to why it is so popular is simple; it was the sample rate chosen for the Compact Disc, and thus is the sample rate of much audio taken from CDs, and the default sample rate of much audio ...
44.1 KHz vs. 48 KHz audio recording sample rate - Page 2 of 2

For example, if you record at 44.1 KHz then up sampled to 48 KHz for use in DVD, etc. then the audio quality is still same because the original recording is done at 44.1 KHz. Remember that you cannot further add “more realism” to your recordings if you didn’t capture it well in the first place.
audio - Why do we choose 44.1 kHz as recording sampling ...
https://dsp.stackexchange.com/questions/17685/why-do-we-choose-44-1-khz-as-recording-sampling-rate
The limit of human hearing is approximately 20kHz, which hence requires a sample rate of approximately 40Khz. This is why CDs are sampled at 44Khz. i.e. each second of recording in a CD contains 44,000 measurements of the highest possible frequency contained in the recording.
