Audio Practice Bench
Turn a measured frequency into a note, tap out the tempo of a track, or find a delay time that lands on the beat. Use the guides below to choose a tool for the next step.
Start with a measurement
Tap tempo
Tap once per beat. After three taps, the estimate uses the median of up to eight recent beat intervals.
Tempo to delay
Convert quarter-note beats per minute into timings for a delay or a reverb pre-delay.
- Quarter
- 500 ms
- Eighth
- 250 ms
- Dotted eighth
- 375 ms
- Eighth-note triplet
- 166.67 ms

Check pitch and singing range
Sing a steady note at a comfortable volume, then try a short scale. Track notes you can repeat on a second attempt. Keep the lowest and highest comfortable notes separate from the extremes you can hit once.
- Read a sustained note with Pitch Detector or Online Pitch Detector.
- Measure your comfortable endpoints with Vocal Range Test or Singing Range Test.
- Use Vocal Range Calculator to work with note names you already know.
More voice and range tools
- Repeat the range check with Vocal Range Tester, Voice Range Test, or Vocal Range Finder.
- Use Voice Type Test as a starting point. Compare where a phrase feels comfortable across several keys.
- Compare speaking pitch with Voice Frequency Test or Deep Voice Test. Read the same sentence each time for a more comparable sample.
Find the beat of a track
Use a section with a clear pulse. If two readings differ by about a factor of two, count aloud over a few bars and choose the beat that matches how you would play or write the part.
- Start with Music Tempo Finder or Tempo Finder.
- Tap out the tempo and explore a key you already know with BPM Key Finder.
- Check your tempo with BPM Calculator or Tempo Calculator.
Work out notes and chords
If a guitar voicing fits more than one chord name, compare the bass note and the chords on either side. Try the progression on the instrument before settling on a name.
- Look up a guitar voicing with Guitar Chord Identifier or work with note sets using Chord Calculator.
- Try alternate progressions in Chord Progression Maker.
- Check violin strings one at a time with Online Violin Tuner. Standard tuning from low to high is G3, D4, A4, E5.
Set up and shape a recording
Run a short take before recording the full part. Compare levels with the same device and mic placement, then listen for lag while monitoring. When using tempo-based effects, audition them against the dry track.
- Compare input levels with Sound dB Meter. Treat readings from an uncalibrated mic as approximate.
- Measure acoustic round-trip delay with Sound Latency Test. Compare setups using the same speaker and mic placement.
- Try a different key with Online Pitch Changer or choose a starting pre-delay with Reverb Calculator.
