Simple and easy high quality digital recording

When matched with an autotriggering ultrasonic detector such as the Pettersson D240x, iriver digital player/recorders enable an effective and easy method for high quality automatic monitoring of bat echolocation calls.

IFP series iriver player/recorders have a line-in jack for recording incoming audio data and a synchronization function that automatically records each bat pass as a separate file. Simply download your acquired files to your computer via a USB cable, convert the files, and you're ready to process your files with SonoBat. The 512 MB units readily support an entire night of recording, and are available for approx. 120-140 USD.

Longer term recording arrangements are possible with higher capacity units such as the iriver H320. These and other recording units can be configured using Rockbox open source firmware to record at specified times, autotrigger, write files with a date and time stamp, and record using lossless data formats.

The SonoBat Batch Attributer utility can attach notes, attributes, and site-specific filenames to your AutoRecorded files.

Although ideal for wildlife recording, iriver no longer produces the IFP series units. However, they can still be purchased through outlets such as ebay. Newer models limit recording capability, most likely over concerns regarding copyright infringement. Other digital recording products to consider include the Edirol R-1.
