Tap tempo BPM calculator and beats-per-minute to milliseconds converter. Sync delay, loops, and metronome timing for music production workflows.
Calculate delay and reverb times in milliseconds synced to tempo and BPM. Find quarter, eighth, and dotted note delay values for any song speed.
Calculate decibel levels, dB addition, voltage-to-dB conversion, and SPL at distance. Compare sound pressure ratios for audio and acoustics work.
Total samples equals sample rate multiplied by duration. Resampling changes sample count but preserves duration when pitch is unchanged.
Samples = sample rate × duration (seconds)Converting rate A to rate B scales sample count by B/A. Proper resampling interpolates new samples; naive speed change alters pitch.
New sample count = old count × (new rate / old rate)Maximum representable frequency is half the sample rate. 44.1 kHz captures up to ~22 kHz; 96 kHz up to ~48 kHz.
Nyquist = sample rate / 2Updated: July 2026
A 120-second clip at 48 kHz has 5,760,000 samples. Resample to 44.1 kHz yielding ~5,292,000 samples with same 120 s duration.
One minute at 96 kHz = 5,760,000 samples per channel — plan disk space at ~2× 48 kHz PCM file size.
A 4-bar loop at 44.1 kHz must be resampled, not stretched, to match a 48 kHz project tempo — verify sample-accurate length after conversion.
Use dedicated resample or export-at-new-rate functions. Simple clip speed change alters pitch and timing relationships.
Set project rate to your delivery target and convert all assets on import. Mixed rates cause pitch/tempo errors or forced real-time resampling.
Digital audio sample rate defines how many samples capture each second of sound. Convert between common rates (44.1, 48, 88.2, 96, 192 kHz) to check duration changes, sample counts, and compatibility for mixing and delivery.
