Data (IQ) File Format
Most SDR programs save IQ recordings using the WAV file format. The disadvantage of this format is a maximum file size of 2GB on Windows, so long recordings required:
- Many smaller (<= 2GB) files,
- Logic to playback this files as a single recording.
Since the start of SDR software bandwidths have grown significantly for 192kHz of the SDR-IQ to 10 MHz with the Airspy R2 or 50 MHz with the Lime SDRs, so an alternate format is desirable. Fortunately this already, exists - WAV RF64.
This format is based on WAV with a maximum filesize of approximately 16 exabytes (1 million terabytes). SDR Console supports recording and playback with the WAV RF64 format, however some popular IQ analysis/playback programs do not support this format. If a program cannot play back a WAV RF64 then you must create the recording using the WAV format. A typical error message when WAV RF64 is not supported is 'Invalid RIFF Headrer'.
Data (IQ) Recording
When you start a Data (IQ) Recording the file format is shown when you select the individual file size.
When you create a Scheduler Definition look at the Single file (WAV RF64 format) option.
