Sound file formats & uploads

Uploading & playing sounds, including automated upload script.

What saved formats are supported for playback?

MP3 (.mp3), WAV (.wav, ulaw/.ul, alaw/.al), SLN (.sln).

What format should I upload for best quality?

Upload a .wav file, or a .mp3 file of 96 Kbps or better. .wav files will be converted to .sln, and that file will be played when no explicit file format is specified at playback.

Where do files show up that I upload?

All uploaded sounds are in the sounds/ directory. If a file named welcome.wav was uploaded, the Playback command would be:

Playback(sounds/welcome)

Note that newly-recorded files must also be saved to the sounds/ subdirectory. See Recording Calls. Cloudvox also provides hundreds of ready-to-use Built-In Sounds.

Do I need to specify a format?

When recording, specify the filename extension; format is derived from that. See Recording Calls.

When playing a file, no extension is needed; Streamfile or Playback will look for a file named with a supported extension. See Language Reference for more.

Can I upload files via an API?

Yes. See Upload Sound Files API docs.
