Hey guys,

Anyone interested in:

LOWER CPU USAGE? ;D ;D

I’ve reworked the back-end clipper, and the results are in:

Same great audio quality, slightly better peak control, AND lower cpu usage.

As measured on a Celeron 420 machine (1.6 GHz, single core) with 512mb ram and Windows XP:

BBP, 0.90.64 and older:

cpu optimized mode: 65% cpu load
maximum quality mode: 86% cpu load

BBP 0.90.66 and forward:

cpu optimized mode: 50% cpu load
maximum quality mode: 65% cpu load

I don’t have one handy to test with, but it SHOULD work on most Pentium 4 computers now!

Download the latest version from:

Thank you leif , the last version 0.90.66 run with lower cpu usage on my system.

With my pentium dual core 1,8ghz , 30% of usage. 😉

you can hear the result here : http://radiopop.relay-network.com:8012/listen.pls

Awesome!

Can we have some benchmarks from some P4, and some AMD users? Would be very interesting. 🙂

Sounds very, very good! Also very loud. Which setting do you use?

I wish you had better bandwidth. It’s basically impossible to listen over here in usa.

Cool, that works great. It’s too bad the relays won’t use the same stream id, or that their relays are not public, because they don’t cluster on shoutcast with your stream. Oh well. 🙂 Sounds nice.

Hot tip for you:

Get this lame
http://homepage.ntlworld.com/jfe1205/LA … 3.90.3.zip
replace the lame_enc.dll EdCast is using now.

Open the config file for the encoder profile, change these values like so:

code :LameQuality=0 LameLowpassfreq=19000 LameHighpassfreq=0 LAMEPreset=12

…and you should get a higher quality stream. With that codec and those settings, I’ve done 128kbps streams that sound better than the 192kbps you have right now. So your 192kbps will see a jump in quality without a doubt. 8)

Sounds better for sure. I can also tell which mp3s you have that are encoded with Fraunhoffer, which cuts off almost everything above 16kHz, even at 320kbps. 😛 It’s quite a crappy codec compared to Lame.

Was looking for a Broadcast processor for a long time !
I found it !!! Awesome !!!
Great job Leif !

It runs on my PIV 650 (3.4 Ghz) with 30 % CPU usage…

What about doing a VST plugin version ???
It should be great for mastering job..

There will be a mastering clipper in the future. But that’s it. Multiband *ANYTHING* in my humble opinion should NEVER be used in anything one would dare to call "mastering".

Some people who rely on cheats like that which RUIN albums call it mastering. But it’s just not. I’m probably one of the most diabolically obtusely opinionated people you’ll ever meet, when it comes to dynamics. Because of being a career radio processing and mastering engineer. 😛

In radio, I’m always pushing for the absolute latest in the bleeding edge, for quality and what will allow for that extra little "edge" against the competition.

But for mastering, I’m an absolute purist. I have literally *never* used compression on a single master that I have ever done. Just protection limiting, if I’m forced to (i usually am), and no more than 1-2db peak RMS limiting, ever. And yet…. my work ends up sounding almost as loud as ANYTHING else on the rack. Ruining the dynamics is clearly not the answer to the loudness puzzle.

Anyways… I’m glad you found Breakaway. 8)
