Turns out that the speed of a Pi 2 is only about 2-2.5% of that of my laptop :( which means that we can't do much with it.

But, we can do some light processing on it. More info tomorrow!

That would be as Americans say awesome, but most importantly very helpful to companies like mine using the device for soundscaping purposes.

BETA774-008

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 74-008.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 74-008.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 74-008.dll

Raspberry Pi 2:
http://www.stereotool.com/download/ster ... ETA774-008

CHANGES:
- "Auto" synchronization mode - Stereo Tool attempts to detect if synchronization is needed by comparing sound card names. Might cause problems...
- Added Raspberry Pi 2 version (requires jackd2, uses NEON support so only works on Pi 2).

OLD CHANGES:
- New feature: Spectral Balance Compensation
- Bug: Winamp plug-in crash: set 'plug-in host latency' to a high value FIXED, was a threading/timing issue
- Bug: Console version: Error: -k: Key <xyxyxyxyxyxyxyxyx> is invalid. FIXED but I don't understand why!
- Bug: GUI: If I set the quality slider to 50 or lower with Ignore High Frequencies set lower that 19kHz the FM output meter goes blank FIXED (I hope)
- Bug: Plus a new one...If I set the stokemask use area slider to zero multiple parts of the processing chain throw exceptions. --> I don't see this one but value 0 makes no sense anyway, I've changed the slider so it cannot go below 50% anymore.
- Bug: FM doesn't get turned off anymore when selecting a non-FM preset, this means that pre-emphasis stays enabled among others.
- Password login shows what you type - should show ******
- Bug: UECP PS/RT texts are sent through the Stereo Tool RDS parser, shouldn't be. -> Probably fixed, but I cannot test it (no UECP encoder here).
- Stokkemask Strictness was set to 2 by default, must be 3.
- Bug: 64 bit stand alone Windows crash, exception 0xc0000005, address 0x000000000000339b (WINMMBASE.dll) - might be a Windows 10 or driver problem! (see below, might be a Windows 10 bug or a driver issue) -> Confirmed, it cleaned up after some Windows updates.

TO BE DONE:
- Half-way busy with improving the Dequantizer - Done, but make it work again in the normal build and
- DFT pre-allocate memory!
- Fix Thimeo engine busy - some bugs left to fix - still more issues to be fixed. OS_WAITEVENT(hq_continue) might be placed incorrectly (not same for chain and chain_hq) or might not be needed at all. OS_WAITEVENT(hqThreadDescription[number].process_ready_event) to be checked. Why does the CPU meter stay close to 100%? That must be a bug. Move Performance meters to see where this happens. Audio is ok though in both plug-in and stand alone. Still broken but at least kinda usable now. Problems: Optimized code doesn't run (stereo_tool.cpp, warning). Sometimes shift in timing. Hangup when switching to different latency, then switching from Thimeo to old framework. EXACT PROBLEMS: Hangup when switching Thimeo OFF in Latency 256. Sometimes hangups when switching at latencies 2048 and 4096. Sometimes jump-in-time at sound card restart after switching between Thimeo on/off (potentially only after changing size first?). Problem seems to be fixed now (at least on 1 latency setting) except for 1-second WAIT loop sometimes (FIXED), and optimized code isn't used (FIXED). Winamp version also asserts after a while. All versions hang on too high CPU load hangs (FIXED).
- ACR Stereo weird effect at latency 128, test track 'Drank & Drugs". - Was highpass filter, removed (for now!)
- Auto-reduce GUI speed when CPU load is too high.
- Enter license key: Add a 'Get from clipboard' button
- Show warning when sample rate is too low for stereo/rds
- Add new Bass In Your Face filter.
- Set separate clipping level for normal output.
- Dequantizer: Make the effect configurable for the lib build. And make it more configurable (final filter vs. first filter).
- Server: Protect against memory reallocation fails when zooming out of waveform display (one of the few places where I allocate memory after starting).
- Add AF method B via UECP!
- Nu is er de optie bij UECP “Use internal settings on connection drop”, dit lijkt goed te werken. Echter als de verbinding weer is hersteld, komen niet direct de gegevens ingesteld via UECP terug. Pas alle settings overnieuw worden gestuurd, zijn deze weer aanwezig in de 9SG. Zou dit niet gebufferd kunnen worden en zodra de connectie terug is, dit worden weer gegeven?
- Make it possible to output lower FM output level in plugin when outputting L/R deemphasized.
- Check Delayed Bass Clipping: Relative sensitivity. Doesn't work according to Bojcha.
- Bug: Hans I think that you forgot the unrecoverable NAN error when adjusting the ND frequancies. I got exactly the same behavior in both of the multibands.
- Bug: Stereo Tool together with JACK Audio, for whatever reason as soon as I activate ASIO in 7.7x, it just quits out and doesnt open up anymore. Note that this even happens when the JACK server isnt even started up. Oh and I use the 64bit version because the 32bit version cant connect to JACK at all, it just says it failed, in the 64bit version at least it used to work fine. (I'm guessing that this is a Jack bug though - will test it here).
- Add a big warning when sound card buffers get too full or too empty about enabling Synchronization.

LATER:
- Bug: Mac: After closing About box, main GUI remains unusable. And it's too small. Suggested fix: Disable for now, make a better About box later. Should be part of the planned Mac native GUI design.
- Bug: Mac: If you click the Help Button it will close Reaper. Not sure if this is supposed to happen. Also the Help-URL is not existing. Also part of the planned Mac native GUI design.

Thanks for the new version, Hans!
Since we jumped from beta 1 to beta 8, are the mentioned changes the only ones or are there some undocumented in between?

Lots of copying back and forth between the Pi and my laptop, hence the jump in version number.

Holy Shit.

An RPI version.

Hans, I love you.

I see that I forgot to add the Raspberry Pi 2 link, added it!

ODROID-C1+ has more power than Pi 2.

ODROID-XU4 is a Samsung Exynos5 Octa, which you probably should be using for this.
