Access files from a computer

Save to Computer

Saving a Voice Monitor file to your computer allows you to free up storage on your device without losing your recordings and data. You can later restore the file to the same device or to a different device. You might also save a Voice Monitor file to your computer if you wish to extract the audio files for analysis in another app such as Sonneta.

Extracting audio files

Sonneta for Mac can import Voice Monitor files directly. When you do this, all calibration information will be retained for measuring SPL. If you wish to use other software to analyze voice samples, you can extract the individual audio files (recordings) from the Voice Monitor file.

Voice Monitor stores recordings in Core Audio Format (CAF) files. This format utilizes Apple Lossless compression to reduce file size and save storage on your device. CAF files can be played in the Finder, iTunes, QuickTime, Sonneta, or many other apps on a Mac. They can be played in iTunes, or a number of third party apps on Windows. Several free and paid apps on Windows (including iTunes) are also able to convert CAF files to WAV files.

The .caf audio files will be named with the date and time at which the recording was made. For example, 2015-05-31_16.05.45.caf means the recording was started at 16:05:45 (local time) on May 31, 2015. If the filename ends with 'Z', then the time is expressed in GMT instead of local time.
