Change Sample Rate
Menu: Effects
Use this function to change the sample rate of a whole audio file. This may be needed to convert a DAT
recording at 48 kHz to 44.1 kHz for use on an audio CD.
After choosing the new sample rate you can select a filename for the new project.
If the resolution is increased, the sample rate change will take place without almost any quality loss - the
sample material will not experience fidelity reductions. (The needed hard disk space will increase
though.)
If the resolution is reduced, the overtones or high frequencies may be lost during the sample rate change.
For example, if the resolution of a 44.1 kHz sample is reduced to 22.05 kHz, the frequency response of
the resulting sample is reduced to 11.025 kHz. The frequency response is always half of the resolution
specified.
Please note that resampling to 44.1 kHz can also be done while recording in real-time.
The Playback Parameter window (Shortcut: p) contains a Varispeed option for real-time resampling
during playback. The Record window (Shortcut: r) will let you resample to 44.1 kHz in real-time from
any of the selected sampling rates.
New Sample Rate
Enter the new sample rate or select from one of the presets.
Quality
This setting determines the anti-aliasing quality during the reduction of the sampling rate and whether the
reconstruction filtering (Interpolation) is to be applied when increasing the sampling rate.
An interpolation algorithm is used, which is also applied during the real time resampling.
High
This adds a filter to dampen the aliasing frequencies or to improve the reconstruction (Interpolation).
Especially when using extreme conversion ratios, such as converting from a 48 kHz signal to a 22 kHz
signal, this setting may improve the results.
Very High
This setting uses a new algorithm, which internally utilizes a higher sample rate. The input and output
sample rates are divisible by this internal sample rate. (For example, the conversion from 48 to 44.1 kHz
uses an internal sample rate off 7.056 MHz). This ensures the highest possible quality.
This method is also used during CD-Bouncing if the sample rate of the project isn’
t equal to 44.1 kHz.
