Find the cleanest BPM and rows-per-beat combinations. See samples-per-row, timing jitter, and quality ratings to optimize your song's timing precision.

Current Analysis

The info tab shows your current BPM and rows-per-beat with a full timing breakdown. See exactly how many samples per row, the remainder fraction, and whether your combo produces jitter.

  • - Samples per row: 60 x 48000 / (BPM x RPB) at 48 kHz
  • - Row duration in milliseconds for timing reference
  • - Jitter measurement: max per-row variance in microseconds
  • - Quality rating: EXACT (zero jitter), NEAR (<1%), or OK
  • - Suggests clean RPB alternatives for your current BPM
