Studio Delay Pocket is an offline BPM timing sheet for producers, DJs, musicians, and live-sound users who need quick delay and loop numbers. Use it to: - convert BPM into quarter-note milliseconds - calculate straight, dotted, and triplet delay values - estimate loop length for a chosen bar count - set a reverb or slap pre-delay from a percent of the delay time - share a plain-text timing sheet during a session Why people pay for it: - timing math interrupts creative work - the app is narrower than a full DAW utility and works offline at the desk or stage - no microphone, audio processing, MIDI, account, ads, analytics SDK, subscription, or server dependency Studio Delay Pocket is a timing calculator only. It does not record audio, process audio, detect live tempo, control plugins, or connect to studio hardware.
