BPM/RPB Calculator
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
Combo Finder
The finder tab shows a searchable, filterable table of BPM/RPB combinations. Narrow by quality, BPM range, and RPB value to find the perfect match.
- - Quality filter: ALL, EXACT only, or NEAR+ (low jitter)
- - BPM range: adjustable from 60-300 in steps of 10
- - RPB filter: ANY (1-128) or specific values (4, 6, 8, 12, 16, 24, 32, 48, 64)
- - Search box filters by BPM, RPB, or quality text
- - USE button applies the selected combo directly to your song
