Change Sample Rate (offline)
The effect processing is done destructively as an offline effect in the audio file of an object. See Applying effects offline
This feature lets you change the sample rate of an audio file. This process is also called "Resampling".
Resampling changes the number of recorded samples per second. If the sample rate is increased, the change is made almost completely without loss. Extra samples are interpolated and the file size increases. When changing to a lower sample rate, some samples are removed and the file size decreases. This results in a loss of overtones.
For the phase setting, you can choose between Linear Phase, Intermediate Phase and Minimum Phase. For most use cases, the Intermediate setting delivers best results. When you want to have a better preservation of the phases of the audio at all frequencies, you can chose Linear, for the price of the introduction of pre-/post-ringing at the transients. With the setting Minimal the transients are best preserved, but then the fluctuations of the phases in the lower frequencies are larger.
Note: Sample rate adjustment can also take place during recording or playback, for example during object resampling, when using audio files with a sample rate different from the project sample rate, or when using Varipitch.
