…and we unlocked 72 dB/Oct filters in freeware version! Check them out (they don’t sound as sharp as they look)
Let’s talk a bit about compressor transfer function used in TDR Nova.

Well, TDR Nova 1.0.5 update was out some time ago and now it seems the plugin is somehow working. The CPU usage is higher than average but we slowly dealing with it. UI is CPU heavy too due to software rendering used but we’ll fix it in some further update.
But let’s talk a bit about differences between TDR Nova and original Nova 67P:
- Overall sound. In “Eco” mode roughly matched original Nova 67P.
- Parallel filters. Mostly the same. In “Precise” mode slight non-linearity added. Frequency range extended to 10 Hz .. 40 kHz.
- High-pass filter. Different. Optimized for sharp curves but maintaining smoother sound at the same time (unfortunately we excluded 48 dB/Oct, 72 dB/Oct, 96 dB/Oct and 120 dB/Oct filters from freeware version). Added 6 dB/Oct HPF slope but removed 18 dB/Oct.
- Low-pass filter. Different. The same as high-pass. Original Nova 67P had fixed 6 dB/Oct slope only.
- Compressor. Different. Has smoother leveling filter, built-in gain reduction limit and hidden release automation. The compressor supports attack values down to 0.1 ms now (or even to 0.01 ms in GE version if “Insane” mode is on). Stereo implementation is 100% linked. Original Nova 67P had 50% stereo link but we changed it to 100% due to lighter CPU usage and wideness added by filters non-linearity. The main advantage of TDR Nova compressor is the ability to have different attack/release and ratio settings for each band. Also GE version supports upward expansion.
- Sidechain filter. Fixed to 200 Hz, 3 dB/Oct. Original Nova 67P had variable sidechain filter taken from Molot.
- Dynamic modes. To streamline the workflow only 4 dynamic modes left: 1) the band follows wideband gain reduction (default), 2) the band doesn’t follow gain reduction (“sticky”), 3) the band has its own compressor, which uses attack/release and ratio settings from wideband compressor (“split” is off) and 4) the band has its own compressor with its own settings (“split” is on). We removed “emphasis” and “50%” modes.
- Analyzer. Based on 1/2 octave bandpass filters (it’s not FFT). We found that such analyzer implementation provides very precise representation of dynamic aspects of the sound. Original Nova 67P had 1/3 octave bandpass filters.
- Stereo modes. We added mid, side, left and right modes but removed unlinked stereo mode.
- CPU usage (on my old Athlon 7750 bought in 2009): Original Nova 67P, “Mastering example”: 5% (plugin window is closed), 35% (plugin window is opened). TDR Nova (“precise” mode), the same settings (see below): 14% (plugin window is closed), 25% (plugin window is opened). Original Nova 67P was planned as some kind of a channel strip but in TDR Nova we shifted the focus to mastering usage, which explains higher CPU usage and smoother sound. Both plugins use 64-bit floating point internal processing. TDR Nova has 32-bit floating point inputs/outputs due to JUCE framework specifics but this restriction doesn’t affect the audio quality and the difference lies below any reasonable audible threshold (output wav files are 32-bit floating point anyway and audio interface receives 32-bit floating point too).
- And finally the UI. Original Nova 67P had minimalistic “paper draft” look. While TDR Nova UI looks more 3D, we tried to keep the colors used and also the amount of curves on the display to minimum. So it’s minimalistic in some sense too.

BPB’s Top 40 Freeware VST Plugins Of 2014!
A couple of words about top 3 effects.
I had pretty interesting concept of a mixture of parallel equalization and splitband compression in one plugin but the approach was just of pure interest without any realistic vision of final plugin. The plugin was created for KVR Audio Developer Challenge 2014 in a great hurry and under very stressful conditions. Some parts were created in less than a hour and the most complex part of this project was to bring all components together and quickly create some kind of acceptable GUI. So we have what we have. The sound of the plugin is good, the plugin is really helpful in many complex mixing/mastering situations but GUI usability is far from ideal. That’s why we’re going to re-release this plugin with enhanced workflow and with some new features under Tokyo Dawn Labs. Also I’m very happy with my 2nd place on KVR DC14 too! And also thanks to Lesha for the current skin.

I can’t say, I did a lot for this plugin. In my opinion the most remarkable contribution from me was complete removal of feedback path (lol) and maybe a little help to RMS part (which led to high CPU usage we finally have). But in GE version I had a great pleasure to implement FDR, variable slope HPF and equal loudness stuff. Also our conversation with Fabien about the name of this plugin was very fun!
It was really joyful experience to collaborate with Herbert on this project and to program DSP code for it and also to add such nice things as EQ saturation, Soviet mode and auto gain stuff. For GE version I’m still not 100% sure (about 75% actually) for the decision to add tilt filter instead of the 4th band but finally we have unique linear shape tilt, great workflow I’m happy with and also with such small additions as Japanese mode, a couple more saturation types and new HPF/LPF stuff! I like standard freeware version due its extreme simplicity and I use it a lot (although I have GE version too). The CPU usage is higher than desired but we tried to reduce it in recent 1.1.0 update.
See you next year!
- Added compressor bypass parameter
- Default preset now has stereo mode setting
- Fixed a couple of possible crashes due to race condition bugs
- New skin by Lesha
