Ampliflare Audio: Studio-quality sound, no studio needed. Remove background noise, balance volume, and cut, split, or convert recordings in one simple app (AGPL)

[u/thepurpleproject]

Release of v0.1.0 of Ampliflare Audio

I’ve been restoring old lectures and videos. A lot of them have rough audio, and some came as FLAC or OGA files. Converting them online was slow and kept interrupting the work.

I went back to Audacity. It can do almost anything, but its interface wore me down. I wanted to process a file, listen to the result, make another change, and move on.

I spent a week looking for other tools. What I found would have cost about $80 for noise removal and another $20 for conversion. The $100 wasn’t the main issue. I wanted something more accessible for people starting out or working on a nonprofit project like mine.

So I built Ampliflare Audio around that workflow. It has five tools:

• Remove noise from speech.
• Enhance audio by evening out volume and cutting low rumble.
• Cut a recording to the part you need.
• Split a recording into pieces.
• Convert between formats, including less common ones like OGA.

You can process batches of files, listen in the app, follow progress, and find your results in Activity. It saves new files and leaves the originals alone. Everything runs on your computer and available to download directly on Windows, Mac and Linux.

DeepFilterNet3 and FFmpeg do the heavy lifting. I’ve put them into an app you can install and use without setting up those tools yourself.

The source is under the AGPL and is free to build and use, including for commercial work. The ready-made app is free for personal use, up to 20 files a week. For commercial use, a pay-what-you-can license starts at $5 and removes that limit.

I want to keep making software the old-school way: install it, open it, and get on with the work. If Ampliflare Audio helps you, please consider supporting it. I’d also like to hear how it works for you.

Pay what you want is currently under a limited time - I might change it to a fixed price and remains a one time payment.
