Improving audio quality

You can improve the overall audio quality of your recordings by changing the sampling rate on the System Settings page.  You may select 8 khz (low), 11 khz (medium), or 22 khz (high) – the greater the number, the greater the sampling rate.  However – there’s a trade-off:  a higher sampling rate produces a larger file (which means more storage space and longer transmission times).  For normal usage, set the File Compression setting to “Post Compression”.  This will compress the .iaf file to 1/10 th the size of a .wav file.  For more info, please go to or
