The Historical Divide: 44.1 kHz (CDs) vs 48 kHz (Video)
In 1980, Sony and Philips selected 44.1 kHz for the Compact Disc (CD) format because it was compatible with both NTSC and PAL video tape recorders used for digital mastering.
Conversely, the professional broadcast and digital video industry adopted 48 kHz because it divides evenly into standard film frame rates (24, 25, 30, and 60 fps), ensuring perfect audio-video lip sync.
Does 96 kHz or 192 kHz Actually Sound Better?
Human hearing maxes out around 20,000 Hz. Under the Nyquist theorem, a 44.1 kHz sample rate accurately reconstructs any frequency up to 22,050 Hz.
While 96 kHz is valuable during studio recording to prevent aliasing when applying heavy non-linear DSP distortion, final distribution at 44.1 kHz or 48 kHz is acoustically transparent to the human ear.
Step-by-Step Tutorial
Identify Your Output Media
Use 48 kHz for any project accompanying video (YouTube, films) and 44.1 kHz for standalone music CDs.
Avoid Unnecessary Sample Rate Conversions
Keep your audio project at its native recording rate until final master export.

Frequently Asked Questions
Why does audio drift out of sync with video in Premiere or Final Cut?
Audio drift almost always occurs when 44.1 kHz audio is placed onto a 48 kHz video timeline without proper sample rate interpolation.
Does DocSwift resample audio when trimming clips?
No! DocSwift maintains the exact source sample rate and bit depth of your uploaded audio file.
