Hello everyone,

I am currently working on a project to measure the impact of industrial noise on the biodiversity of a natural reserve in Veracruz, Mexico. I have been utilizing SongMeters m2 and AudioMoths for my research. However, I am considering a new recorder manufactured by LabMakers called SongBeam (description link and source code provided below) due to its cost-effectiveness.

During the testing phase, the device appeared to function satisfactorily. Nevertheless, upon examining the four-channel recorder, I observed two discrepancies: first, two channels exhibited excessive noise across the entire frequency spectrum (as depicted in the accompanying image), while the other two recorded relatively cleanly. Given that the recording was conducted in a controlled environment, this type of noise is not representative of the natural environment. Second, all channels exhibited significantly low volumes. While this issue can be mitigated by amplifying the signal, I am seeking assistance in adjusting the volume settings. Initially, I suspected that this was an audio software issue, but both Audacity and Raven were unable to resolve the problem.

I would appreciate any assistance from individuals with experience in utilizing this software. I have already contacted the device’s designer, but I have not yet received a response. Thank you for your consideration.
