Building useful web tools, AI workflows, and SEO-driven products.

Hi, I’m Edmund. I’m an independent maker building practical web tools, AI workflows, and SEO-driven products. I’m interested in how small tools can solve specific user problems — from audio and music tools to calculators, automation systems, content workflows, and niche SEO websites. I use this blog to share product ideas, building notes, SEO experiments, tool reviews, backlink research, and lessons learned from my own projects. Current projects include AI audio tools such as mp3tomidi.pro, along with other niche web tools and automation experiments.

The “can I hum the melody in this clip?” test is the right first filter, and I agree that MP3 vs WAV is usually not the thing that decides it. A clean hummed hook or a short piano phrase will beat a pristine WAV of a dense master.

When the only source is already a finished mix, though, trimming to a “clearer” eight bars often still leaves drums, bass, and pads under the line. The converter then has to guess which of those should become notes. A more reliable extra step, before the short-section workflow you describe, is to isolate the intended part first (a vocal or lead stem from Demucs, UVR, or a similar separator) and run audio-to-MIDI on that file. You still treat the MIDI as a draft — fix durations, octaves, and extra notes in the DAW — but the input is closer to the “one clear musical idea” case the model actually handles.

If you were adding that to the table, would a pre-isolated vocal or lead stem sit with “usually good,” or do you still see enough bleed and reverb tails that it belongs with “needs cleanup”?
