Built for Quality & Privacy

AllToolsNow ボイスレコーダーが選ばれる理由

Engineered from the ground up using native HTML5 Web Audio DSP and client-side LAME encoding. Faster, safer, and cleaner than conventional server-dependent recorders.

100% Client-Side Privacy

All audio capture, buffering, and encoding take place strictly inside your browser sandbox. Your voice recordings are never sent to any external server or saved in the cloud.

Real-Time Waveform & VU Meter

Monitor microphone activity dynamically with a smooth 60fps glowing oscilloscope and calibrated peak dB volume meter with red clipping warnings to prevent harsh distortion.

Unlimited Duration

No artificial caps or 5-minute limits. Record hours of university lectures, board meetings, voiceovers, or musical rehearsals reliably without interruptions.

True WAV & Genuine MP3

Unlike basic online tools that falsely rename WebM containers as MP3, our tool constructs real 16-bit uncompressed RIFF WAV files and compiles genuine LAME MP3s with valid headers.

Studio Acoustic DSP

Toggle browser-level acoustic echo cancellation, environmental noise suppression, and automatic gain control on or off depending on whether you are dictating or recording musical instruments.

Keyboard Hotkeys

Operate the recorder entirely without a mouse. Hit the spacebar to start, pause, or resume, press Escape to stop and finish, or hit Delete to discard bad takes instantly.
