Studio Tools
A pocket lab for timing, tuning, and other perfectly normal obsessions.
Session settings
Saved on this device23.976, 29.97, and 59.94 use exact /1001 rates.
Changing tasks keeps your entries. Unit changes convert the current quantity. Unrelated unit families remember their own values. Starting points and Reset replace settings. Unit changes need valid values within the destination range.
A starting point replaces the current settings. Save your setup first if you want to keep it.
Your setups
Tempo & note length
Delay times, modulation, metronome practice, and score duration.
Tap at least three times. A pause over four seconds starts again.
The tap button also works with Enter or Space when focused.
- Milliseconds
- 250 ms
- Nearest whole sample
- 12,000
- Cycle rate
- 4 Hz
Method & limits
BPM counts quarter notes. Sample counts are rounded to the nearest whole sample.
Pitch & transposition
Frequencies, tuning ratios, chord compatibility, and written versus concert pitch.
- Nearest note
- A4
- Frequency · Hz
- 440 Hz
- Offset · cents
- 0
- Shifted frequency
- 440 Hz
- Frequency ratio
- 1×
Method & limits
12-tone equal temperament. Positive cents are sharp. This calculates a ratio. It doesn’t analyze or retune audio.
Samples & time
Move between an edit offset and its duration.
- Samples
- 480
- Milliseconds
- 10 ms
- Rounded duration
- 10 ms
- Rounding error · µs
- 0
Method & limits
Time is per channel. This is sample-count math, not a sample-rate converter or a measurement of system latency.
Levels & decibels
Plan a gain change, convert levels, or check integer PCM precision.
- Linear gain change
- 5 dB
- Headroom to 0 dBFS
- 6 dB
- Crest factor
- 12 dB
- RMS after gain
- -13 dBFS
Method & limits
Uses measurements you supply. RMS must use full-scale amplitude as its reference, without AES17 sine calibration (+3.01 dB). A gain change preserves crest factor and does not compress. Sample peak is not true peak. This does not measure LUFS or guarantee an encoded file will not clip.
Compression model
Compare a static curve and a target reduction. Check timing against the beat.
- Modeled output
- -15 dBFS
- Modeled reduction
- 9 dB
- Threshold for target
- -14 dBFS
Method & limits
Hard-knee, steady-state model without makeup gain. Attack/release values are note-length references, not recommended settings. Detector type, envelope, knee, and program behavior are deliberately outside this model.
Attack reference / Release reference
Attack reference: 31.25 ms · Release reference: 250 ms
Signal bench
Check pan-law sums, a phase model, or a first-order RC circuit.
- Gain per channel
- 0.707107
- Combined power vs one hard side
- 0 dB
- L + R sum vs one hard side
- 3.01 dB
Method & limits
Identical mono signal routed to both channels. L + R is unnormalized. This is a center-only check, not a complete panner curve or a prediction of perceived loudness.
Frames & timecode
Timecode, shutter exposure, and frame-rate conform math.
- Non-drop-frame
- 00:01:00:00
- Frame count
- 1,440
- Elapsed seconds
- 60
- One frame · ms
- 41.666667
Method & limits
Exact /1001 frame rates. DF skips labels, not picture frames. Source offset is zero. There is no automatic 24-hour rollover. This is duration math, not a time-of-day clock. Changing frame rate keeps the frame count and updates the label. Elapsed time changes. Switching input format or DF/NDF keeps the same frame count.
Picture & print
Canvas sizes, crops, print PPI, and screen density.
Only canvas dimensions change. These are aspect-ratio starting points for video, social posts, and tablet layouts. They do not specify device screens or guarantee platform safe areas. Interface overlays and crops vary by placement.
- Scaled image · px
- 1,920 × 1,080
- Scale
- 50%
- Padding · Left / right · px each
- 0
- Padding · Top / bottom · px each
- 0
Method & limits
Square pixels and a centered image. Dimensions are rounded for display. Cropping or padding is measured on the output canvas. No image file is changed.
Quick conversions
Lengths, durations, and storage units without leaving the session.
- Converted value
- 3.280839895 ft
Method & limits
Exact defined unit factors. Storage distinguishes decimal kB/MB/GB from binary KiB/MiB/GiB. No exchange rates or live data.
Delivery size
Estimate the payload before a render or transfer.
- Estimated payload
- 51.84 MB
- Binary size
- 49.438 MiB
- Total bitrate
- 2.304 Mb/s
Method & limits
Payload only. Container, metadata, and filesystem overhead are excluded. Encoded size assumes the entered average bitrates. MB uses 1,000,000 bytes and MiB uses 1,048,576.
