Frequently asked questions
When would I need 48kHz instead of 44.1kHz?+
48kHz is the standard for video and film work; 44.1kHz is the CD/music-streaming standard. Match whichever pipeline you're delivering into.
Does upsampling improve quality?+
No — resampling to a higher rate doesn't add detail that wasn't in the original; it just matches the sample rate a target system expects.
