Everything you need to know
The Web Audio API gives modern browsers a full audio processing pipeline — decoding, filtering, gain control, and rendering — that runs faster than realtime. Our tools use this to do professional-grade edits entirely on your device: no upload wait, no privacy risk, no file size limits beyond what your RAM can handle.
iPhone ringtones must be under 30 seconds. Android notification sounds work best at 3–10 seconds. WhatsApp and Telegram tones at 5 seconds. The Audio Cutter's waveform editor lets you find the perfect hook, trim it to the exact length, and export as MP3 with fade in/out for a polished result.
Old recordings, phone voice memos, and legacy MP3s often sit 10–15 dB quieter than modern masters. The Volume Booster amplifies up to +18 dB with an optional soft limiter that tames peaks before they clip — the same technique used in broadcast audio chains.
MP3 at 192 kbps is the practical choice for sharing, ringtones, and podcasts — small files, universal compatibility. WAV is uncompressed 16-bit PCM — larger but lossless, ideal for archiving and further editing. Because we decode to 32-bit float internally, WAV export preserves exactly what the browser decoded.
