5. In CODE3W CFG you can enable or disable Keep_Recording_After Mode Enabling it with YES will keep audio recording Also if a decoding mode is closed or more modes are running with audio recording The default value is currently YES because in this way all decoding and audio tools become independent Clicking the PAUSE button in main FFT window stops the recording but does NOT close and save the audio file that only happens when you click on the start stop audio button again To conserve space on the hard drive and to ensure files are not too large to be transmitted via a LAN the CODE3 32 automatically cuts each audio recording into separate files according to a setting in the configuration file No data is lost as each file overlaps the others by a short amount of time The default setting for the amount of space dedicated to each file can be changed by modifying the MAX _AUDIO_FILE_SIZE entry in the configuration file Besides the independent audio recording function already discussed there are two other audio modules which act as decoding modules and can be started and closed by the IP Mode The two modes are called Radio Quality and Telephone Quality Radio Quality samples at 11 025KHz and Telephone Quality at 8KHz The Telephone Quality Module offers a 4 KHz audio bandwidth which saves Space on the hard disk this allows for very long recordings of up to several weeks Due to the lower sampling speed of this module
