I'm releasing a modified version of the Pd-based voice training tool intended for use in voice training for trans masc people.
My husband is going through voice training at the moment, and was already using the original version of this tool. By request, I've created a modified version that, rather than beeping when you go below a target pitch, beeps when you go above it. In other respects, the tool is identical.
You can download it here:
Unless you already happen to have it installed, you also need to download the Pd (PureData) audio synthesizer engine, which is free. You can get in here:
Pure Data — Pd Community Site
Miller S. Puckette’s “vanilla” distribution of Pd
To set the pitch at which the tool beeps, the box marked 'Low Freq', which defaults to 150, can be changed. You can either click on it and edit the number, or click and drag up or down to tweak it as you use your mouse. If you want to save your changes for next time, Save As... from Pd's File menu will do that.
As always, this is free to download and do whatever you like with. I hope it helps!
