Audio & Music Creator Tools
High-precision tools for music producers, beatmakers, audio engineers, podcasters, and independent artists. Calculate exact BPM tempo and delay sync tables, cut audio clips with millisecond precision, extract soundtracks from video, and validate album release cover art against DSP requirements.
BPM Tapper & Delay Calculator
Tap along to find any track's BPM. Computes full producer delay, reverb pre-delay, and modulation milliseconds.
Audio Trimmer & Cutter
Cut MP3, WAV, and OGG audio with an interactive canvas waveform visualizer, loop playback, and fade curves.
Cover Art Checker (Spotify / Apple)
Audit your album artwork against official DSP guidelines: 3000×3000px, 1:1 ratio, RGB JPG, and file size limits.
Video to Audio Extractor
Extract voiceovers, stems, and soundtracks from MP4, WebM, or MOV video files directly to lossless audio.
Syncing Delay & Reverb to Song Tempo
When setting delay feedback times or reverb pre-delay in music production, un-synced milliseconds introduce frequency masking and muddy up the mix. At 120 BPM, a quarter note is exactly 60,000 / 120 = 500.0 ms, an eighth note is 250.0 ms, and a sixteenth note is 125.0 ms. Setting your reverb pre-delay to a 64th or 32nd note ensures the dry vocal punch hits cleanly before the acoustic space blooms.
