One click
Press Start Mastering. The engine measures your loudness, runs a full mastering chain and delivers release-ready WAV, FLAC and MP3 files with a waveform preview and instant playback. That is the whole workflow.
The profiles
25 masters. 25 vibes.
Zero guesswork.
Each profile is a complete hand-tuned chain: EQ curves, compression, saturation, stereo shaping, reverb space and two-pass loudness targeting. You do not adjust a single dial. You just hear the result.

For podcasters
Take your podcast audio to the next level.
- Every episode lands at the same broadcast loudness. Two-pass LUFS targeting means episode 1 and episode 51 sit at identical volume. No quiet episodes, no clipping, no listener riding the volume knob.
- Studio presence from any mic. Podcast Studio Clean removes hiss, tames sharp esses and adds the dense polish of a broadcast booth.
- Rescue bad recordings. Recorded on a phone or a bad call? Phone / Remote Fix was built exactly for that.
- Upload-ready files. Export the formats podcast hosts ask for, at the loudness they want.
For producers
Songs that keep the vibe you made.
SoundHustl Master does not flatten your track into a template. Each song profile is a hand-tuned chain of EQ, compression, saturation, stereo width and space that pushes your mix toward release quality while keeping the character you built. Master a single, an EP or your whole back catalog in an afternoon.
- Genre-aware chains, from Chicago Blues Warm to Berlin Techno, each with its own loudness target.
- True-peak safety. Loud where it should be, clean where streaming platforms check.
- Instant A/B. Preview the original and every master side by side before you export.
Why it sounds right
A real mastering engine.
A toy-simple interface.

Questions
Everything else you
might be wondering.
What is audio mastering?
Mastering is the final polish before release: balancing loudness, controlling peaks, shaping tone and making a track sit right next to commercial releases on Spotify, Apple Music, YouTube and podcast apps. SoundHustl Master does the whole job for you in one click.
Do I need to be an audio engineer?
No. If you can drag a file and click a button, you can master. The profiles carry the expertise: each one is a complete chain tuned for a genre or a voice style. You just pick the one that matches your material.
Is my music uploaded anywhere?
Never. SoundHustl Master runs completely offline on your own computer. Your songs, episodes and voice memos never leave your machine, and the app works without internet.
Which formats can it read and write?
It reads WAV, MP3, FLAC, AAC, M4A, OGG, AIFF and even video files like MP4 and MOV, extracting the audio automatically. It writes 24-bit WAV, FLAC and MP3 at 128, 256 or 320 kbps, all at 44.1 kHz.
What exactly does the $4 buy?
The free plan masters anything, as much as you want, and exports the first 2 minutes of each master. The $4 Pro license unlocks full-length exports for 31 days. There is no subscription and nothing renews on its own: when the month ends, you decide if you want another.
Does it work on my computer?
Yes. SoundHustl Master is a small desktop app for Mac (both Apple Silicon and Intel) and Windows 10 and 11. It is not a plugin, so it does not matter which DAW you use, or whether you use one at all.
What is LUFS and why should I care?
LUFS is how streaming platforms and podcast apps measure loudness. If your audio is off-target it gets turned down or sounds weak next to other content. SoundHustl Master measures your file and lands it exactly on the target, every time, automatically.
