Mix (Rock)

The first three files comprise one example, which shows the loudness potential of the Gyratec XXI. In the third pass I am using the mid-range band to reduce the harsh guitar resonance around 2kHz, to create an even rounder sound picture.

01: Original

02: Full-range Clipper Thr 3 o'clock Level 2 Full, Red

03: Full-range Clipper Thr 3 o'clock Level 2 Full, Red, Mids at 2 kHz

Mix (Jazz)

This jazz ballad is ideal material for the Gyratec XXI. The mix is rich, diverse and dynamically complex. Again, this material shows the loudness potential of the device, and the 'Red' pre-emphasis curve helps preserve the rounded punchiness of the bass. In the final pass, the multi-band section reduces resonances in the percussion elements. Note how this brings out the room sound on the rim click!

01: Original

02: Full-range Clipper Thr Low Level 2 o'clock, Red

03: Full-range Clipper Thr High Level 2 Full, White

04: Full-range Clipper Thr High Level 2 Full, Red, Mids at 1.4 kHz, Highs at 4 kHz

Drums (acoustic)

In this example comparatively soft settings on the Gyratec XXI help to enhance a poorly mixed drum-bus signal. Again, the Gyratec XXI reduces peaks, and the snare sound in particular gets thicker and more 'massive'.

01: Original

02: Full-range Clipper Thr Low Level 2 o'clock, Red

03: Full-range Clipper Thr Low Level 10 o'clock, Red

04: Full-range Clipper Thr Low Level 12 o'clock, Red, Bass at 50 Hz, Mid at 270 Hz, Highs at 4 kHz

Drums (electronic)

This example shows varying degrees of processing on a programmed drum loop. Note the different relationships between bass drum, snare and cymbals.

01: Original

02: Full-range Clipper Thr Low Level 12 o'clock, White

03: Full-range Clipper Thr Low Level 12 o'clock, Red

04: Full-range Clipper Thr Low Level 12 o'clock, Red, Lows at 200 Hz, Highs at 5 kHz

Bass drum

This bass drum signal proves how powerful the Gyratec XXI can be when used on individual instruments. The unprocessed bass drum has a strong attack spike (probably from a compressor with a long attack time) that can be drastically reduced using the G21. The second pass is optimised for equal loudness, and the third pass is normalised to prove once more the loudness-processing potential of the Gyratec XXI.

01: Original

02: Full-range Clipper Thr 3 o'clock Level Full, Red — equal RMS

03: Full-range Clipper Thr 3 o'clock Level Full, Red — normalised
