Pick +6, +12 or +18 dB, download a louder MP3. Runs in your browser; the file never leaves your device.
Three steps. Zero uploads. The entire pipeline runs in your browser tab.
Click the drop zone or drag a file in. We read it locally — no network call is made to open it.
FFmpeg's volume filter runs inside a Web Worker via WebAssembly. No server round-trip, no queue.
Grab the new file with one click. Everything stays local until you choose where it goes.
Boost applies one flat gain increase — simple and predictable. Loudness normalization measures the file and adjusts to a target, better for uneven recordings. When in doubt, normalize.
Yes — boosting past 0 dBFS clips. Start with +6 dB; if the recording is still faint, step up. The normalizer avoids this by design.
An MP3 at 128 kbps named <name>-boosted.mp3, raised by the amount you picked. Boosting past full scale clips, so start at +6 dB.
No — the boost runs via ffmpeg-wasm in your browser.
The first click loads a 32 MB WebAssembly build of FFmpeg. Your browser caches it, so later runs in the same tab start at once.
50 MB per file, because the work happens in your browser's memory. A longer recording does not need this step to be transcribed: WhipScribe takes one file up to 10 hours or 5 GB as it is.
