Converting sample rate...
The Sample Rate Converter resamples audio to a different sample rate — 44.1 kHz, 48 kHz and the other common rates. Sample rate sets how many times per second the audio was captured; matching it to your project or platform avoids playback-speed and sync problems.
Music and podcasts usually target 44.1 kHz; video production commonly uses 48 kHz. Resample once to the right rate before delivery.
To change the sample rate of a file, choose a target and the tool resamples cleanly — downsample a 96 kHz capture to 48 kHz for video, or convert 48 kHz to 44.1 kHz for a podcast or music release. Matching the sample rate to your project or platform is what keeps playback at the right speed and keeps audio in sync with picture.
Use 44.1 kHz for music and most podcasts, 48 kHz for audio destined for video. When matching an existing project, use the project's rate.
Above 48 kHz the difference is inaudible for finished delivery and just makes bigger files. Higher rates mainly help during heavy processing, not playback.
