This voice recorder lets you quickly record notes, create stickies with voice notes attached, or send recordings as email attachments. Files are saved in QuickTime format, so play on Macs and PCs. QuickVoice’s interface is compact and comes with several attractive skins. You can create as many as ten channels, each containing as many as 99 messages of any length. Audio files can be disk hogs, but QuickVoice lets you change the sample rate and choose from several compressors to adjust the size and quality of your files.
