J-Dawgs Audio Fixer™

What it is

Audio Fixer is a web app you open in your browser — no download, no install, no account. You drop in an audio file and it shows you the waveform plus the file's real measured loudness: peak and RMS in dBFS, with a plain-words verdict ("way too quiet," "healthy," "already clipping"). One tap on Fix Loudness renders a leveled version — gain staging plus compression/limiting, peaks held under a −1 dBFS ceiling — and shows you a measured before/after table so you can see exactly what changed.

Then you listen before you commit: an A/B switch plays the original and the fixed version back to back. Save as a genuine 24-bit WAV or a genuine 256 kbps MP3 — encoded in the app, never a renamed file. Got a whole set of voice memos or podcast takes? Batch mode levels them all to the same target in one pass.

Unlike a live volume booster, the fix is in the file. It sounds right everywhere, forever — not just while some booster app stays open. When you buy it, you also get it as a single HTML file you can keep and run yourself. One payment of $7.99. Yours forever.

What it does

• Real measurement first — waveform with trim handles, true peak and RMS read from the actual file buffer, in numbers and in plain words. Nothing is invented or estimated
• One-tap Fix Loudness — three targets (Gentle −18, Standard −14, Loud −9 dB RMS), rendered offline through a compressor/limiter; a final ceiling pass guarantees no sample passes −1 dBFS, so the fixed file cannot clip. Verified before sale: on a worst-case spiky file demanding +10.9 dB of makeup gain, the fixed peak landed at exactly −1.00 dBFS
• Measured before/after table — the app reports the actual change it made, in dB, measured from the rendered file
• A/B listen before you save — hear the original and the fix, then decide. No fix is forced on you
• Trim, fades, silence-trim — with undo, so an edit is never a one-way door
• Batch mode — level a whole set of recordings to the same target in one pass, with per-file status
• Honest exports — genuine 24-bit WAV (PCM) and genuine MP3 (256 kbps, encoded in-app). MP3 export is included, never paywalled separately
• Runs anywhere — in the browser on your phone or computer, works fully offline after it loads, and as a single downloadable HTML file that's yours to keep. Your files are processed on your device and never uploaded anywhere

The honest limits — printed here and in the app

• File-in / file-out only. It fixes files you open in it. It cannot change another app's sound while it plays — Spotify, YouTube, and streaming audio are out of scope, and the app says so on its first screen.
• Very long files are limited by your phone's memory. The app shows a practical length guide; hour-long files on a low-memory phone are the edge case.
• No "AI noise removal" claim. This app levels loudness and trims — it does not claim to remove background noise, and no version of this page will tell you otherwise.
• Loudness targets are RMS averages: a fixed file is consistently leveled, but how loud it feels still depends on your device and volume. Peaks, though, are guaranteed under the −1 dBFS ceiling.

Who it's for

• Podcasters and voice-memo recorders whose takes come back too quiet or uneven from episode to episode

• Musicians and creators leveling demos, rehearsal tapes, and voice notes before they share them

PRODUCT: J-Dawgs Audio Fixer by J-DAWGS INDUSTRIES. WHAT IT IS: a browser web app that permanently fixes the loudness of audio files: open a file and it shows the waveform with trim handles plus the file's real measured peak and RMS loudness (dBFS, with a plain-words verdict); one-tap Fix Loudness renders offline through gain staging and a compressor/limiter to one of three RMS targets (Gentle -18 dB, Standard -14 dB, Loud -9 dB) with a final ceiling pass guaranteeing no sample passes -1 dBFS (verified pre-sale: a spiky 0 dBFS-peak file demanding +10.9 dB of makeup gain at the Loud target produced a fixed peak of exactly -1.00 dBFS, confirmed in the exported WAV's decoded samples); a measured before/after table reports the actual change; A/B listening compares original vs fixed before saving; trim, fade in/out, and silence-trim with undo; batch mode levels a set of files to the same target with per-file status; exports are a genuine 24-bit WAV (RIFF PCM) and a genuine MP3 (256 kbps, MPEG-1 Layer III, encoded in-app — byte-verified, never a renamed file). HONEST LIMITS: file-in/file-out only — it cannot process another app's playing audio (streaming is out of scope); very long files are limited by phone memory (a practical length guide is shown in-app); no AI noise-removal claim is made.
