## What is SUS4 Recorder?

Record a take and see its tempo, with an estimate of its key and chord.
Search your recordings by name, key or chord, so you can find that riff in D later.
Fully on-device: no cloud, no account.

Press record for rehearsals, lessons and ideas. The newest take gets a card with its key, BPM and chord. Add reverb or EQ on playback without changing the original, then share it.

• Records at 48 kHz
• Tempo detection with a key and chord estimate
• Reverb and 3-band EQ on playback, non-destructive
• Library with search by name, key or chord
• WAV export, share by AirDrop, Files or any app

For musicians recording rehearsals and lessons, and songwriters who want their ideas labeled.

Everyone gets five recordings a day. Pro, or SUS4 All-Access across the whole range, removes the daily limit and adds seven more reverbs, chorus, a compressor, drive and M4A export.

Made in the UK by working musicians.
