SupportTeam Report post Posted 01/27/2005 06:48 AM If getting studio recording made it is recommended that you ask the studio to record in their best possible format (eg: 44kHz WAV files). Then you will be able to downsample these to either 11kHz WAV or 8kHz .WAV with little distortion. "VoiceGuide for TAPI" (the version you can download from our WWW right now) uses 11kHz 8bit Mono .WAV files with Dialogic systems. "VoiceGuide for Dialogic" uses 8kHz 8bit Mono WAV files and can also use .VOX files directly (8kHz 4bit Dialogic ADPCM format) It's pretty hard to convert between 11kHz and 8kHz without distortion - that is why you really should make your originals in high quality. NB. Phone lines have a bandwidth of 4kHz at most. Often the bandwidth is much less - especially on mobile connections. Share this post Link to post
