An open-source sound recorder
The C-Sound is a WAVE file logger in the very robust, low-maintenance housing of the F-POD, with a high quality hydrophone, low-noise pre-amlifier, anti-aliasing, lossless data compression and up to 3TB of memory.
Selection of gain, sampling rates 16 - 512k/s, duty cycles and frequency filtering are available.

C-Sound Hydrophone
The C-Sound hydrophone frequency response will be verifed by the National Physical Laboratory, London.
Software and support
The C-Sound produces standard WAVE files that can be analysed using many software packages, such as Audacity, which has a widely used free version, and Raven.
Chelonia does not offer any support or advice on handling the settings of the C-Sound or the data analysis, but will offer calibration as for the F-POD.
C-Sound v SoundTrap
These instruments do similar things, but there is a significant difference you might not spot in the specifications:
In deployments over weeks and more in some marine locations the growth of barnacles, mussels etc aka 'biofouling' is a big issue. To remove it the simple shape and robust nature of the housing of the C-Sound makes removal much easier with no risk of damaging the hydrophone or any connections.
The C-Sound can achieve longer running times on account of its larger battery pack.
C-Sound v Hydromoth
The HydroMoth is a very neat low-cost logger consisting of an AudioMoth in a transparent plastic case.
The sound path goes from the plastic case into the air inside which loses most of the acoustic energy due to the massive change in density. This makes it very insensitive, but for some applications at shallow depths this may be satisfactory.
The C-Sound offers wider sampling options and better anti-aliasing.
