Why this particular conversion comes up so often
The video-to-music handover
Anything shot on camera arrives at 48 kHz. Anything destined for a music platform, a CD master or many podcast hosts is expected at 44.1 kHz. This one conversion sits on the boundary between the two worlds, which is why it is the most requested rate change in production audio.
Let the conversion be yours
If you upload a 48 kHz file where 44.1 kHz is expected, the platform converts it with whatever resampler it happens to use, at whatever quality it happens to offer, after your loudness pass. Converting yourself keeps that decision, and the audition of the result, on your side.
Professional use cases

Frequently asked questions
- Why convert 48 kHz to 44.1 kHz?
- 48 kHz is the video standard, 44.1 kHz the music and podcast standard. Delivering a 48 kHz file to a platform expecting 44.1 kHz means it gets resampled without your control.
- Does resampling degrade the audio?
- A single conversion is inaudible on dialogue and most music. What does damage a file is chaining conversions, so resample once, at the end of the chain. This tool uses a linear-interpolation resampler, which is well suited to delivery conversions between common rates rather than to extreme ratios.
- Should I resample or change the playback rate?
- Resample. Simply reinterpreting 48 kHz material as 44.1 kHz slows it down and shifts the pitch.
- Can I go the other way?
- Yes: 44.1 to 48, 96 to 48, 192 to 48. Any common rate, both directions.
