The compression algorithm is intentionally "allowed" to fvck around with everything above 1/4 of the bandwidth - because it knows the decimating filter will properly remove that crap later. Now, remove the oversampling and you'll have horrible distortions above 1/4 of your bandwidth, probably everything above 5kHz!

Most interesting concept. So far the result confirms your splendid concept! Thank You!

A huge update is available from the labs website!

Most notable changes include new "release fast" and "release slow" controls. The detector is now adjustable too. I also added a transfer function display and improved the color section.

The compressor is now MUCH more flexible, I hope you like the changes.

I found no time to update the manual yet, but will do soon.

I think the 1.0.0 release will most probably in 2-3 weeks. The mac version will appear a few days later.

I'm am liking this compressor more and more. A top 3 buss compressor with a squeaky clean bullet. Transparent, with a sweet character. Arigato!

The GUI design is very good. It looks very simple but yet very stylish. It's looking even better than many commercial plugins. Whoever did the GUI design did a great job.

the new version is not compatible with the old one.

is v1.0 going to be compatible with 0.9.01 ?

@madoliarian: Thank you!

@filter303: I did the UI myself, glad you like it!

@lesha: You're right, and I'm sorry for the struggle. This was the last compatibility problem with this plugin, promised!

I kinda liked the old meters better, but thanks regardless.

Hi Fabien

I would like to ask some questions but don't feel that I demand any answers, it's just curiosity.

I am trying to figure a few things out when it comes to software processing, most of the time I feel that my best mixes are without any processing besides EQ. I find that besides the ArtsAcoustic compressors I don't really care for software compression. Some of the waves and the two emulations from IK were interesting, but I don't care to buy them as I don't think I'd really use them.

I am tempted by Duende plug-ins though. But why is it that compressors that are not as good as yours can cost so much but yours is free?

Tell me what is it that makes your compressors better than others? (I would just like to hear all the details from you, things going on under the hood that I would never think about).

I just feel like so often the sound gets degraded the more I try to "enhance" it with plugins. This is all using proper gain-staging at 96Khz 32bit on soft-synths and samples.

Regards

Sami

Of course anyone else can chime in

Yes, I made similar experiences with the plugin flood since the last decade.

IMO, audio processing is totally overrated, especially compression. The final quality of a production is most of all related to composition/recording-approach/workflow. The tools don't matter much.

So many flowers!

The main reason is that I have a huge advantage compared to commercially motivated companies. I can invest years of work without fearing deadlines and angry customers.

From the technical point of view, the compressor is very sophisticated. Nice sounding compressors and limiters are much more difficult to build than it seems. The "analogue" approach doesn't work.

I'm not really sure where to start. But the most effective "tricks" are definitely related to the detector, attack/release filters, aliasing reduction and structure of the gain cell (the central multiplication), quantization distortion reduction. There are many things one can do wrong regarding these subjects.

Finally, I think that the UI/User experience is very important too.

For me, plugins are tools. Not more not less. Much like a screw-driver.

"I have a solution, now I'm looking for a problem"

But your feeling is right, you can't imagine how many bad things happen in EQs and comps. Audio processing is much more lossy than most people would imagine. The less, the better

Thanks for your response. I am glad to know I am not a alone with my thoughts about compression etc. As far as a big sound its about the mix, but a good limiter on the end helps too.

Can your compressor be used as a limiter very well?

This compressor is really starting to show promise, especially with the new release times. Really smooth and a good addition to what Ive already got. I can see this getting some serious use... cant wait to see how further development takes it

@Aiynzahev: No, this is one major "drawback" of the compressor. It's a very bad for overload prevention.

There are several reasons for this. The main reason is that the compressor tracks its output, not the input (you can see it with the detection meter, the more you compress, the smaller the detection level becomes).

Because of that, the compressor ratio is basically limited to 3:1

All both stronger ratio settings use a trick to achieve their reduction performance. More than 8:1 is very difficult to achieve with this design.

Additionally, all detectors beside the PEAK mode can't accurately track the (output) level due to their timing behaviour (they are slow).

This compressor fails at limiting. I recommend to avoid the 4:1 and 8:1 ratios for the 2bus anyway.

@Trakstar: Thanks! Keep me updated how it works for you!

Thank you for this update.
Could you tell us a little bit more about the 2 release times ?

Im loving it, its as smooth as butter on drums. Very low threshold with ratio 1.1-1.5 with very fast attack and very fast release time 1 then smoothing out with release time 2. last time i used one like this was kjaerhus audio gold compressor opto mode and I still have it. This works better than my voxengo crunchessor, its what it should have been. 200% harmonic settings and straight on a mixbus. crunchessor is going in the bin. Thanks very much. The last 2 releases are quite different so I am holding on to both. I would have had no problems buying this from you!! Quality

Anyone tried the new TDR Feedback Compressor?
