A Digital Metronome
November 24 2023
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
Matlab Midi Recorder
October 13 2023
Recording your composition in midi format is the most modern way of storing music. The advantages of midi files are too many to count. I am currently working on a project that involves teaching piano to special needs children. We needed a method to evaluate how well the children learn... Read more
A Simple Sound Recorder
October 07 2023
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
October 06 2023
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...

Coding Shall Set You Free
September 16 2023
On the way back from lunch in Mensa on the LMU campus in Martinsried one summer afternoon in 2019, Lutz said to me,” Ravi, I want you to get good at MATLAB® before the end of your Ph.D. You won’t have to depend on anyone if you can write your... Read more
