Beat, bar and phrase lengths at 145 BPM
At 145 BPM one beat lasts 413.79 ms and a 4/4 bar lasts 1.655 s. The beat is not a whole number of milliseconds, so round to the nearest 0.1 ms when you type times in by hand, or use your plugin's tempo sync. That is 2.417 beats per second, or 36.25 bars of 4/4 per minute.
Dance tracks are usually arranged in 8-, 16- and 32-bar phrases. At 145 BPM a 16-bar phrase takes 26.48 s and a 32-bar intro or outro takes 52.97 s. That is 5.52 s shorter than the same 16 bars at 120 BPM. A six-minute track at this tempo contains about 218 bars.
| Length | Time | Milliseconds |
|---|---|---|
| 1 beat | 0.414 s | 413.79 ms |
| 1 bar (4 beats) | 1.655 s | 1655.17 ms |
| 4 bars | 6.621 s | 6620.69 ms |
| 8 bars | 13.24 s | 13241.38 ms |
| 16 bars | 26.48 s | 26482.76 ms |
| 32 bars | 52.97 s | 52965.52 ms |
| 64 bars | 1:45.9 min | 105931.03 ms |
Delay times at 145 BPM
Straight values follow the beat; dotted values are 1.5 times as long and triplets are two-thirds as long. At 145 BPM the popular dotted-eighth delay is 310.34 ms and a quarter-note slapback is 413.79 ms. The Hz column is the matching rate for an LFO, tremolo or auto-pan synced to the straight note.
| Note | Straight | Dotted | Triplet | Rate (straight) |
|---|---|---|---|---|
| 1/1 (one 4/4 bar) | 1655.17 ms | 2482.76 ms | 1103.45 ms | 0.604 Hz |
| 1/2 | 827.59 ms | 1241.38 ms | 551.72 ms | 1.208 Hz |
| 1/4 (one beat) | 413.79 ms | 620.69 ms | 275.86 ms | 2.417 Hz |
| 1/8 | 206.9 ms | 310.34 ms | 137.93 ms | 4.833 Hz |
| 1/16 | 103.45 ms | 155.17 ms | 68.97 ms | 9.667 Hz |
| 1/32 | 51.72 ms | 77.59 ms | 34.48 ms | 19.333 Hz |
Reverb times at 145 BPM
A common way to keep a reverb in time is to tie its pre-delay to a short note value and let the tail fade within a longer one. At 145 BPM a 1/64-note pre-delay is 25.86 ms and a 1/32-note pre-delay is 51.72 ms.
The decay control on most reverbs is RT60, the time it takes the tail to fall by 60 dB, so the audible tail ends earlier than the number shown. Treat these values as starting points and adjust by ear.
| Reverb character | Pre-delay | Decay (RT60) |
|---|---|---|
| Tight room on drums | 25.86 ms | 413.79 ms |
| Medium plate on vocals | 51.72 ms | 827.59 ms |
| Large hall or pad wash | 51.72 ms | 1655.17 ms |
| Ambient tail over two bars | 103.45 ms | 3310.34 ms |
Genres at 145 BPM
145 BPM is in the up-tempo, high-energy range. It sits near the upper end of the techno range (125–150), at the top of the trance range (128–145), at the top of the dubstep range (135–145) and at the bottom of the hardstyle range (145–160).
Heard at half-time (72.5 BPM) it lines up with ambient/downtempo, hip-hop and reggae/dub. A detector or a tag in your library may report either reading, so check by ear which one the drums suggest.
These ranges are common practice rather than rules: genre is decided by rhythm, sound and scene as much as by tempo, and plenty of tracks sit outside the usual numbers.
- Techno: typically 125–150 BPM — from restrained 125 to fast, hard styles near 150.
- Trance: typically 128–145 BPM — a regular kick usually gives a clear pulse.
- Dubstep: typically 135–145 BPM — usually counted around 140 but felt at half-time, near 70.
- Hardstyle: typically 145–160 BPM — most releases sit near 150.
Mixing into 145 BPM
To bring a track at another tempo up or down to 145 BPM, move its pitch fader by the percentage below. Without key lock the key moves too, by the number of semitones shown; about 6 % is one semitone, so changes beyond that are where key lock (master tempo) starts to matter.
A ±8 % pitch fader on a track at 145 BPM reaches 133.4–156.6 BPM; a ±16 % range reaches 121.8–168.2 BPM.
| Track tempo | Pitch change to reach 145 | Key shift without key lock |
|---|---|---|
| 139 BPM | +4.32 % | +0.73 st |
| 141 BPM | +2.84 % | +0.48 st |
| 143 BPM | +1.4 % | +0.24 st |
| 144 BPM | +0.69 % | +0.12 st |
| 146 BPM | −0.68 % | −0.12 st |
| 147 BPM | −1.36 % | −0.24 st |
| 149 BPM | −2.68 % | −0.47 st |
| 151 BPM | −3.97 % | −0.7 st |
Half-time, double-time and nearby tempos
Half-time of 145 BPM is 72.5 BPM and double-time is 290 BPM.
290 BPM is outside the 60–200 range of these pages; the half/double-time converter works with any value.
72.5 BPM falls between two whole tempos, so the nearest pages, 72 and 73 BPM, are linked instead.
Each 1 BPM step at this tempo changes the beat by about 2.83 ms, so neighbouring tempos are close enough to beatmatch with a small pitch move.
Frequently asked questions
- How many milliseconds is one beat at 145 BPM?
- One beat (a quarter note) at 145 BPM is 60,000 ÷ 145 = 413.79 ms. A 4/4 bar is four beats, 1655.17 ms.
- What is the dotted eighth delay time at 145 BPM?
- A dotted 1/8 delay at 145 BPM is 310.34 ms: an eighth note (206.9 ms) multiplied by 1.5. A straight quarter-note delay is 413.79 ms and a quarter-note triplet is 275.86 ms.
- What genre is 145 BPM?
- Techno, trance, dubstep and hardstyle commonly use 145 BPM. Genre ranges overlap, so the drum pattern and sound decide the style more than the number does.
- What is 145 BPM in Hz?
- 145 BPM is 2.4167 Hz when one cycle equals one beat. An LFO synced to one bar runs at 0.6042 Hz, and one synced to sixteenth notes at 9.667 Hz.
