Hi everyone,

As someone who works with audio, I got tired of online mastering services that require creating an account, paying subscriptions, or uploading large audio files to remote servers just to get a quick loudness check or master.

So I built a completely free web tool

🔒 Why it’s different:

• Zero Uploads / 100% Privacy: All the audio processing happens locally inside your browser (using Web Audio API). Your raw files or podcast episodes are never sent to a server.
• No Account Required: No emails, no password creation, no paywalls.
• Instant Speed: Since there’s no uploading or downloading from a cloud server, the output is generated almost instantly depending on your CPU.

Since podcasting requires consistent loudness levels (for platforms like Spotify and Apple Podcasts) and clean voice clarity, I’d really appreciate it if you could test it on one of your raw tracks/episodes.

• How does the master sound to your ears?
• Is the user interface clear and intuitive?
• Are there any specific controls or presets you’d like to see added for podcast workflows?

Give it a try and let me know your thoughts!

I have don't post the link because of spamming if you are interested ask me in the comment

thanks
