Change Sample Rate / Resolution
The Change Sample Rate feature allows you to convert a .wav file from any common sample rate to any other common sample rate. It also allows you to convert from any common resolution (or file depth) to any other common value. These features are provided with a user selectable interpolation quality since improved interpolation takes more CPU horsepower and therefore more time to make the conversions. This way, the user can make this tradeoff. The following controls are provided with the associated ranges of the Change Sample Rate / Change Resolution Feature:
New Sample Rate: 11,025, 22,050, 32,100, 44,100, 48,000, 88,200, 96,000, 192,000 Samples/sec.
Resolution: 8 Bits, 16 Bits, 20 Bits, 24 Bits, 32 Bits FP
Conversion Quality: Choose between –
Note 1: The tradeoff between these conversion quality choices is the time that it takes to make the conversion; higher quality levels of interpolation requires longer processing time.
Note 2: The Conversion Quality used by the Batch Processor is non- selectable and is set to “Master Quality”.
Dither: Choose between –
Note 1: In general, choose Triangular or Noise Shape 2 with your ears helping you to make the decision as to what is best.
Note 2: Usually dithering is used when lowering the bit depth…like going from 24 to 16 bits.
To perform a conversion, bring up the file to be converted in the Source window. Select the desired conversion parameters from the outlined choices. Run the filter and the results will be displayed in the Source window after a period of processing time. The file will automatically be re-named by incrementing its name by a value of one, so long as there are no other files with that same incremented name in existence in the chosen file directory.

Conversion Quality: Choose between –
- CD Quality (16 bit interpolation)
- Pro Quality (24 bit interpolation)
- Master Quality (32 bit interpolation)

Dither: Choose between –
- None
- Flat Spectrum: White noise is used as the dither. This is usually not the best choice unless you are doing analytical work.
- Triangular High Pass: A shaped noise spectrum that does a good job of reducing distortion. The name comes from the type of digital filter used. The noise is biased to the high frequency end of the audio spectrum and is less audible than the flat spectrum dither.
- Noise Shape 2: Our own proprietary noise shaped spectrum. This distribution has less mid-band noise than the triangular spectrum, but more at the high end of the audio band.
