A Digital Metronome

November 24 2023 . Ravi Umadi

Backstory A couple of weeks ago, I walked into a music store in Munich, thinking about picking up a decent metronome for a reasonable price. It turns out, metronomes can be expensive, anywhere from 50 euros to over 200. That would be worth spending for a musician. For someone developing... Read more

As a student of bioacoustics, and working with many devices, I often felt the absence of a quick recording method to access the sound cards and record at high sampling rates. Most of my experimental programs are elaborate and designed for specific tasks. However, obtaining data should not be that... Read more

Low Latency Real-time Playback

In auditory-related experiments, achieving a quick turn-around time with signal processing is an important aspect of experimental design. Whether one wants to playback the same signal as received at the microphone, modify it and then playback, or in yet another paradigm of neuroscience experiments, playback the sounds and record from...

Most field recordings of bat echolocation calls come with reflections from various surfaces, including the ground. However, the direct call arrives first, followed by the corresponding echoes. Here, we explore the primary analysis of echolocation call recordings obtained in the field condition. Analyses on field recordings commonly employ a peak... Read more

How To Record Bats
