These are convenient Spectrum Analyzer combinators to see your song's frequency spectra. Each one has an accurate scale with Band and Hz labels. Since the dawn of Reason, people have been asking for labeled frequency bands, and now we more or less have it! Thanks to Rogerraa and Selig for the frequency measurements!
I prefer the Spectrum Analyzer 32, but in case you don't need that much resolution, I also created a 16 band version.
Watch a video of this Spectrum Analyzer (76 Hz–10.5 kHz) + Spectrum Analyzer 2 (11 kHz–20 kHz) in operation.
User Controls:
- Band Select: 4, 8, 16, 32, FFT (512)
- Decay: Lower = faster display; higher = overall averaging.
- Display Scale: Roll this back to see the peaks.
- Display Hold: Take a snapshot in time.
Place before final output. It's a great aid for balancing your mix!
Vocoder Band Frequencies
These reference charts for all band frequencies, seen below, are printed on each combinator. The frequencies were measured accurately by Allen Day ("rogerraa") and Giles Reaves ("selig") on PUF. Rogerraa did the initial measurements, which were later confirmed and "re-centered" by Selig using an audio analysis program called FuzzMeasure.
| Band | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
| Hz | 76 | 89 | 104 | 122 | 142 | 166 | 196 | 230 | 270 | 318 | 371 | 436 | 510 | 597 | 701 | 823 |
| Band | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 |
| Hz | 962 | 1130 | 1325 | 1553 | 1822 | 2134 | 2508 | 2935 | 3439 | 4037 | 4740 | 5551 | 6509 | 7632 | 8949 | 10500 |
| Band | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
| Hz | 80 | 110 | 152 | 210 | 289 | 400 | 550 | 760 | 1050 | 1449 | 1999 | 2754 | 3805 | 5254 | 7252 | 10000 |
I also created a companion 11 kHz – 20 kHz Spectrum Analyzer 2
