Compressors make me happy. Will test!

Maybe an idea to change the title of this thread to include the name of the compressor so it will show up easier in a search.

Done!

It's working fine here, on core 2 quad with FL studio, 96khz. CPU usage was 12 percent, a little too high for tracking. Sounds really nice, but the "Harmonics" buttons are tame, and I couldn't hear a difference on my speakers. Nice work so far.

Thanks for you input!

Hey camsr, I just uploaded a new version with severe performance improvements. the plugin now runs nearly 2.5 times faster due to SSE2 optimizations! (wtf

)

Still, the plugin is not CPU optimized for higher sample-rates than 48kHz. The CPU will suffer without reason

..I will improve it in the next versions.

The downside is that CPUs without SSE2 aren't supported anymore. Hope you can live with that restriction.

I even slightly increased the gain of HF harmonics.

But note that the harmonics functions are very subtle by design. They don't add much more saturation than proper analogue devices. The HF is less obvious than the LF, most of all because the former only adds even harmonics (octaves). The LF switch only adds odd harmonics, which are easier to perceive.

Uhmm...i think there is a bug in this latest version: it doesn't compress at all. Previous version works great however

P.S. Good compressor! thanks man!

Are you sure? Can you see the reduction meter moving?

What's your setup (CPU/OS/DAW)?

zeep · Post by **zeep** » Mon Mar 05, 2012 4:55 pm

Same here. The meter moves but other than some very weak changes in volume it doesn't compress.

OMG, thank you guys.. ..I found the issue! I set the sidechain gain faaar too low for some stupid reason

Update in a few minutes..

EDIT: Done! Bugfix available

Working great on a core 2 in ableton live 8, a little cpu intensive compared to some other comps, but definitely sounds good. I'm thinking of doing my bus compression with this thing.

Also- TOKYO DAWN

Feedback compressor updated! I implemented several feature suggestions from beta-testers, hope you like it.

download it here: http://www.tokyodawn.net/tdr-feedback-compressor/

Great!
This is getting better and better!!!
Congratulations and thank you!

Thanks!

....but....seems HF harmonics doesn't work at all (maybe a bug similar to the "compressor doesn't seem to compress at all")

Thank you !
What is the "Delta Mode" ?

And one more question : are the HF and LF harmonics volume-dependent ?

FabienTDR · Post by **FabienTDR** » Sun Mar 18, 2012 11:36 pm

Hey alteregoxxx, everything seems alright this time. Maybe the effect is too subtle? It can be difficult to perceive as an obvious effect, it's easier to observe when switching it off. Also, many parts of typical monitoring chains may introduce very similar effects and make it really difficult to hear.

But I just double checked the latest version, here's what I could measure (and looks/sounds as expected):

Here's everything to "off"

Here I enabled the HF harmonics and set them to 200%. The algorithm mostly creates even harmonics ( 2, 4, 6, 8 ), as well as a faster dropping dip of odd harmonics ( 3, 5 ). Note that the harmonics amplitude will increases with frequency (this one shows the effect for a 1kHz input). The exact balance between each harmonic is level and frequency dependent.

BTW, the LF harmonics switch generates a different harmonics pattern (odd harmonics only) and its level decreases with frequency.

The "Delta" switch allows to hear what the compressor "adds" to the original signal. This is the equivalent of mixing the compressors output with the phase inverted original. It's a great way to learn what compressors really do. You'll also be able to hear what the harmonics switches do, but note that the HF harmonics will not be audible most of the time or at least sound very strange. The latter is due to the prominent even harmonics generated the HF section. [/img]

Anyone tried the new TDR Feedback Compressor?
