I’m afraid I don’t know any USB cards that are really good for MPX.
Hey, are you using BBP or BBP ASIO?
I myself have used BBP ASIO for weeks with EMU 0202 without problems.

LeifKeymasterThe beauty of this is that in all cases except software encoding, the interfacing is completely transparent to the application. As long as the sound card presents a 6-channel wave device to the software, it doesn’t matter how the sound card chooses to pass the audio onto the amplifier, whether it’s HDMI, Analog, DTS Connect or DD Live. So, yes — they will all be supported. 🙂
Perhaps you guys can answer another question — when watching TV on your HTPC, does the audio get played through the sound card like any other audio played in your computer? (You can verify this by turning down the Wave volume control slider and make sure the TV audio is affected as well).
If so, I think Breakaway HT is technically possible.

LeifKeymasterIt’s a switch in the I/O settings window.

I have experienced EMU 0202/0404 USB going into a failure mode where the card appears to function perfectly, but no audio comes out. This is either a driver or a hardware problem — I would not recommend these cards in a mission-critical environment.
Pitch-up/Pitch-down is new though, never heard about that.
Breakaway contains an asynchronous sample rate converter, and if the sample rate of the sound card suddenly changes, Breakaway will attempt to resample to keep audio flowing. Breakaway also attempts to restart the audio card if it keeps running at the wrong rate for a few seconds, but it sounds like something must be going wrong with that — or perhaps the card gets into an unrecoverable state?
Anyway, the short answer is that the EMU cards simply are not reliable enough to be used for days on end. It’s important to choose the right hardware for the job. Juli@ cards work great, and so do Marian Trace Alpha cards.

I never joke about my work, 007! 😉It exists. Digitally Imported has been using it on all their streams since 2003. Initially with OctiMax processing, later (2006) with Breakaway processing, long before Breakaway Personal was ever conceived.
It’s a DSP plug-in, but can be run standalone with my DSPQ utility. And sorry, yes, it’s very much private.

LeifKeymasterIt definitely should not be freezing up. What happens exactly? Could you tell us more about your system?

LeifKeymasterThe current version does not support 5.1, however I am considering making a surround-compatible version.
Since you’re looking for 5.1, are you up for some brainstorming to help figure out what people would need to be able to use a 5.1 processor?
5.1 is complicated, because of one important gotcha:
S/PDIF (optical or coaxial), the interlink everyone uses for interfacing their DVD player or satellite box to their amplifier, does not actually support 5.1 PCM audio.
S/PDIF is a 2-channel (stereo) format, and the only way to get 5.1 surround through it, is by encoding the audio into Dolby Digital or DTS, which are both bit-reduced, lossy formats.
When you play a DVD on your computer, the DVD already contains encoded audio, and the player just passes it through without touching it. This of course means that it can’t be processed!
To process 5.1 audio, it has to be decoded to 5.1 PCM audio. This is easy — the DVD player software can do it for us. The question is, once it’s decoded and processed, how do we get it into your amplifier?
There’s a few options:
- 5.1 Analog. Six RCA plugs. I know, pretty much nobody uses that but me. This is a viable option though, for those who have amplifiers with the correct inputs. Many do, but not all.
- HDMI from the computer to the amplifier. HDMI does support 5.1 PCM, and it’s a viable option for those who have computers with HDMI outputs, as long as they’re configured correctly.
- S/PDIF from a computer with Dolby Digital Live or DTS Connect encoding built in. Some computers have this, but not all. It slightly reduces quality, so it’s less desirable than the above options, but still viable as a last resort.
- Encoding the audio in software with a Dolby Digital or a DTS encoder. This would work on any system, but adds delay, reduces quality, and worst of all, licensing the encoder is hideously expensive — out of range for a consumer product. That’s why no consumer gear contains an encoder.
So, to sum it up, I could make a surround-compliant version — the difficult part is how to get the audio into your amplifier. Of the options above, only the first 3 are feasible, which means there WILL be systems it simply will not work on, for example, a computer without HDMI or built in encoding, and an amplifier without analog 5.1 input.
Comments? Would it work in *your* system? Please let me know.
The Breakaway core algorithm does support 5.1, and I’ve also invented a nice stereo to 5.1 upmixer, which you simply must hear. I use it in 5.1 mode all the time, and it’s also being used on numerous HDTV stations in the USA and around the world. So, if it can be packaged into a consumer-digestible format, I have no doubt you’ll like what you hear 🙂.
Best regards,
///LeifLeifKeymasterI wish it wasn’t so complicated to license codecs, or I would have released LeifCast a long time ago.

LeifKeymasterI designed the controls to have exaggerated range. I’ve learned it’s the only way to do it, as if you limit the range of controls, people will put them at the very edge (like 0 or 100) and feel limited. As it is now, setting them all the way in either direction is pretty much guaranteed to be a bad thing — things are much more reasonable towards the middle.
The New York Preset is very cranked as it is. It sounds good at about -2 final drive (that’s minus two, not plus two). I absolutely wouldn’t go above the default 0 on it — there’s just no way it’s going to sound good. Don’t forget to look at the oscilloscope when tweaking, to get a feel for what you’re actually asking the audio processor to do. 🙂

LeifKeymasterSet Breakaway Live to Broadcast Mode (not Speaker Mode) and it will be enabled automatically.
Best,
///LeifLeifKeymasterBreakaway Live absolutely has pipelines — in fact is has three of them 🙂.
However, the pro products do not alter the system settings automatically, so you’ll have to either set the Pipeline as the Windows default sound device, or set Winamp to output specifically to the pipeline you want to use.
Best regards,
///LeifLeifKeymasterAll Breakaway Pro products have adjustable low-pass filter!
I recommend Breakaway Live for HD Radio.
Best,
///LeifLeifKeymasterOf course! It’s obvious what the problem is.
The code, as it’s written, will just increase the account number, without doing anything to the contents.
What you want is to increase the value of the number it’s pointing to, not the pointer itself.
code :for a = 1 to 100000
rem add 1000 euro to my account
*MyAccountNumber = *MyAccountNumber + 1000
next aThat should do it!
