Ten audio formats, a waveform drawn at one line per pixel, and settings that actually change the file on disk. No ads, no accounts, no tracking.
Coming soon to Google Play
Every control here changes the audio that lands on your device — nothing is decorative.
WAV in 16-bit or 32-bit float, FLAC, MP3, M4A, AAC, OGG, Opus, AMR and 3GP. Sample rate up to 96 kHz and bit rate up to 320 kbps, with only the values each format genuinely supports offered.
Drawn one hairline per pixel with a time scale above and below, so the peaks line up with the moments that made them. Colour and grid are yours to set.
Drop silent stretches as you record, or capture only while someone is speaking. Both have adjustable thresholds, and the timer counts only what was kept.
Edit on the device. Trimming copies the stream rather than re-encoding, so a 320 kbps file stays 320 kbps. Convert between any of the supported formats.
Gain from −30 to +30 dB, noise suppression, automatic gain control, microphone selection and direction, mono or stereo, and monitoring through headphones while you record.
Pause or stop automatically on an incoming call. Recordings are written to private storage first and recovered after a crash, so an interrupted session is not a lost one.
Optional PIN or biometric unlock, re-armed whenever the app leaves the screen. PINs are salted and hashed, never stored as text.
Turn on the built-in server and download recordings from a browser on the same network. Password protected, and off unless you start it.
Build the filename from the parts you want — date, time, milliseconds, prefix — in the order you want, in your own time zone. Rename on save if you prefer.

This is the whole story, and the privacy policy says the same thing at greater length.
There is no sign-in, no advertising and no analytics of any kind. The app contains no tracking libraries.
Recordings are never sent anywhere. The only network feature is the Wi-Fi server you switch on yourself, which serves files on your local network and nowhere else.
If you enable location tagging, an approximate place name is stored with the recording on your device. Leave it off and no location is ever requested.
