Tempo Converter

Convert a musical tempo into Hertz, seconds, milliseconds and timecode for effects, chasers and timecode work.

TL;DR

“From BPM to Hertz, seconds and timecode - in realtime and offline.”

Core Capabilities

• From BPM to Hertz and Seconds
  Enter the tempo in BPM and the number of beats per bar to instantly get the beat and bar frequency in Hertz, as well as the length of a single beat and a single bar in seconds and milliseconds - ready to be used as effect or chaser speed.
• Plan Whole Sections
  Combine full bars with additional beats to get the exact length of any part of your track. Every result is also shown as timecode (hh:mm:ss:ff) at the selected framerate, so timecode sections stay in sync with the music.

Step-by-Step

1. Set the Tempo:
   • Enter the tempo in Beats per Minute and the number of Beats per Bar (Measure) of your track.
   • Choose the Framerate used for the timecode results.
2. Define a Length:
   • Enter the number of Full Bars and, if needed, Additional Beats for the section you want to measure.
3. Just Read the Results:
   • All values update automatically in real time - no calculation, no confirmation needed.

Important Information

Note

The base value for all calculations is the length of a single beat in seconds (60 / BPM). Everything else - bar length, frequencies and section lengths - is derived from this value.

One bar (measure) consists of the given number of beats. To get the length of a partial section, combine full bars with additional beats. For example 1 bar and 2 beats in a 4/4 tempo results in one and a half bars.

Frames are rounded to the nearest whole frame, so a beat that does not fall exactly on a frame boundary is displayed at its closest possible frame.

User Interface

Tempo and Length

• Beats per Minute: The tempo of the track (1-999 BPM, two decimals).
• Beats per Bar (Measure): How many beats form one bar (1-128). Use “4” for a 4/4 tempo.
• Framerate: The framerate used for all timecode results (24, 25 or 30 FPS).
• Full Bars: The number of complete bars of the section you want to measure.
• Additional Beats: Additional beats added to the full bars (three decimals for partial beats).

All results are updated in real time while changing values.

Results

• Base: The beat frequency (1 beat = Hz), the bar frequency (1 bar = Hz) and the duration of a single frame (1 frame = ms) at the selected framerate.
• One Beat: The length of a single beat in seconds, milliseconds and as timecode.
• One Bar: The length of a single bar in seconds, milliseconds and as timecode.
• Bars + Beats: The length of the defined section (full bars plus additional beats) in seconds, milliseconds and as timecode. The row label reflects your current input, for example “1 Bar + 2 Beats”.
