Format, Sample Rate, and Bit Depth

Omnisphere can import standard, uncompressed (PCM) stereo or mono .wav, and aif files of any sample rate with bit depths of 8, 16, 24, and 32.

Certain files, such as those with advanced compression, cannot be imported. If you receive an error message, simply convert the file to a standard, uncompressed (PCM) .wav, or aif file format and re-import.

NOTE: The import user audio feature in Omnisphere does not support 32-bit floating point audio files.

Base Note

Omnisphere will read the base note (the key on which the sample will play in its original tuning) when importing an audio file.

You may specify the base note number by either including it within the audio file as a base note attribute; or name the file with the base note at the end of the file name, preceded by an underscore or space:

Audio File Name_D#3.wav or Audio File Name D#3.wav.

If both the filename specification and the embedded base note attribute are present, the base note from the filename takes precedence.

NOTE: A base note is not required in the file name. If omitted, the software will use any existing base note attribute embedded in the audio file. If a base note has not been specified, the default is Middle C.


Omnisphere will play looped audio files, but the loop points must be embedded in the audio file before importing. Many audio editors have this ability, such as Magix’s Sound Forge, Steinberg’s WaveLab, or DSP-Quattro (Mac only).
