Explanation

UltraVox XT accepts audio files of format PCM, encoded at 16 bits and with a Mono channel.

Solution

If the audio file was recorded stereo, or encoded with 24 bit resolution, convert it to PCM WAV file format, mono, 16 bit, using an audio-editing application such as Audacity, available on the internet. Next, import the converted file in UltraVox XT.
