Audigy 4 native sampling r
I own the original Audigy 4, and have a few questions about the Audigy 4's nati've sampling rate.
) What is the actual?nati've sampling rate of the Audigy 4? Is it 48K, 96K, or both??2) Is it true that the Audigy 4 can?NOT record and play back nati'vely at 44.K without using internal resampling?Does?"internal resampling"?mean that the driver is downsampling on the fly to 44.k whenever I record an analog signal in my host app at 44.k, or does the card have a chip that does this at very high quality?3) Assuming it is true that the Audigy 4 can not handle 44.K nati'vely, then If I record and mix 48K, and then use a good quality software resampler to convert the final master to 44.K, will I be getting professional results. Or should I bite the bullet and get a soundcard that does not do internal resampling. If so, then any recommendations?Thanks,?J.Message Edited by JReality on 07-5-20070:6 PM
The nati've sampling?for the included DSP is 6bit/48KHz. You can bypass the DSP if you don't use any CMSS effects - it will use the DMA engine that can handle anything up?to 24bit/96kHZ (or 92kHz in stereo only) with no resampling.Resampling to 96kHz is loseless, only the one at 44.KHz is painfull Editing the signal in the PC?will not be affected by DSP, that resampling is only for the signals that leave the sound card via analog out.http://en.wikipedia.org/wiki/Audigy#Second_Generation

Third party instruments, samples and/or effects?
Hey All,
is it possible to add new drum samples, instruments, or effects to Garageband for Ipad? I am really happy with the program, but i feel that in time the native sample- and effect packs will start to bore me.
best,
JensIf you upgrade to GarageBand 2.0.5 you can buy the Red Loops, available for a limited time this week only.

AA 3 vs CS6 playback sample rate
Is there a way to ask CS6 to playback at the native sample rate, automatically, instead of resample? AA 3 would always playback at the native sample rate, if supported by the hardware, while CS6 resample even if the sound device supports the sample rate.
CS6 switching between projects I have to manually look at the sample rate, then change the hardware settings.
Thanks!
DavidI think it's an operating system problem you've got here - Windows is notorious for resampling anything it thinks it can get away with. There's a setting on the audio hardware page that attempts to link Audition and the sound device hardware rather more firmly, but your best bet absolutely is to use an external sound device that uses ASIO - this bypasses most of the OS completely, and generally doesn't have these problems.

Does the ATV3 re-sample audio files to 48kHz?
I've read here that all audio files are played back at their native sampling rate (44.1kHz) using an ATV 1. With ATV 2, all audio files are re-sampled, unfortunately, degrading sound quality, from 44.1 to 48 kHz. Is this still the case for the new ATV 3?
Tell Apple what you think of this here:

I am having a number of issues including loss of import functionality from scanner, I can't drag and drop photos into the editor any more as well, or at least not after the first one. The crop function stops working after the first couple of photos. Then some freezing. A little added crashing. A plethora of other bizarre issues as well. This just stated happening a couple of days ago.
What I have tried:
Uninstall/Install.
Deleted preferences both before opening Editor (crontrol-alt-delete) and after opening it.
Kindly advise. Thanks!

OK! Check it, like I said in previous posts I seemed to have narrowed it down to specific mp3s not converting and playing in their native sample rate which if paired with another sample would give you the "audio midi sync" error and basically screw up your clock! It appears mp3 files converting to mp3 using iTunes would not convert to the correct sample rate if set to something other than 44 in logic and cause this. A tad peculiar Apple iTunes won't work with Apple Logic. I was able to confirm this on two mac's via my friend in Florida. He's running Tiger and tried the same experiment and Booya! Mickey Mouse! It appears this insane week long adventure has came to an end (...god willing) with a super specific unlucky shot in the dark on my part finally revealed to be an perfectly normal function of Logic (obviously one i'm not fond of..) As far as the errors / crashes / system overloads / kernal panics I think I can sort those out to the mackie onyx satellite not being a good choice and trying to add and remove firewire devices in the middle of the sample rate mayhem. Wow! all I can say is, I'm glad it's over
Wish me a lot of luck in the future.. I'm sure i'll need it! -
The Sorry State of Sound In Linux
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
READ: http://insanecoding.blogspot.com/2007/0 … linux.html
I've only discovered this because of an ALSA bug was making my life miserable. That article was written about a month or two before OSS4 (Open Sound System v4) was released under GPL and CDDL. This past January, it was released under BSD as well. Unfortunately for the developer, he does not understand open source very well. He is now reporting that his revenue went significantly down..
OSS4 does not equal to the crap OSS in Linux 2.4 kernels. Even OSS3 != OSS3 in former linux kernels. He was neglecting the open source version in favour of the commercial one. Instead of improving it, someone forked it. And, the fork became popular. Unfortunately, the original author had no interest in working on the fork. So, he only focused on the commercial version. Now, many years later, the commercial version is fully open source. There is no more commercial version.
I've tried it, and I really like it. Music sounds much better than on ALSA. For example, screaming in alternative rock is more legible. It's like enabling "enhance voice" in a phone. It supports higher PCM values without noise.
The mixer (vmix) is capable of 18 channels. It can also do per application volume control (like PulseAudio).
It totally makes sense that OSS gets back into the kernel because it works on almost every UNIX and UNIX-like system (except OS X). ALSA only works on Linux, and according to that article, developers still prefer the OSS API, even on ALSA. However, the ALSA OSS API is lacking according to an ALSA developer. I can confirm that the comment on the ALSA OSS Emulation API working better than the ALSA API. XMMS with ALSA enabled freezes my system. XMMS with OSS enabled on ALSA does not.
It worked without any configuration besides muting some channels to kill the noise.
THE BAD
ossmix and ossxmix are totally unusable because they do not name the channels properly. ossxmix uses 100% CPU if Compiz is enabled. Version 4.1 will fix this.
I had to figure out WTF ossxmix.codec1.connector.jack14.jack 54:54 means. Sane names need to be added to the jacks such as "mater, front, input, auxiliary, microphone, etc.."
It's best to use ossxmix (GTK+ mixer) and playing with all the jacks to figure out what each one does.
One interesting control is how OSS4 should behave (Fast, Medium High, Professional, etc.). It's probably a latency control. ossxmix is a demo app on how you can control the mixer from GTK. It needs to be made usable.
If you use Media Player Daemon, VLC, and MPlayer, OSS4 works beautifully. They use OSS directly. Others have problems.
Totem does not play sound. Totem-Xine uses 100% CPU (Xine-UI works with low CPU usage).
In terminal I noticed some output from oss mixer control saying it received bad arguments. OSS4 is backwards compatible with OSS3, but xine-lib may be using the API badly.
The progress bar (seeker) in GStreamer based applications (Rhythmbox, Banshee) does not work if you use vmix, or it may work, but it will be unsure of the length of a song. You will see it constantly adjusting a few seconds up or down. By the middle of the song, the length reporting generally stabilises. You have to enable softoss (the old mixer). vmix and Gstreamer behave very badly. The Gstreamer developer responsible for OSS claims that it does on his system. Though, he is most likely using the trunk version.
You have to apply this patched gstreamer to make volume control in GNOME work.
While the progress bar problem is fixed with softoss, volume control does not work, even with the patched GStreamer. It only works with vmix. System > Preferences > Sound lists nothing under "Default Mixer Tracks".
Sound does not work in KDE4 at all. While Phonon is based on Xine, which has OSS support, it queries HAL, which does not support OSS4 yet. Therefore, it thinks that there is no sound card.
As for KDE 3.5.9. Amarok works, Noatun works, and anything based on MPlayer should work. KMIX does not work. Same in KDE4.
DOWNLOAD IT (Popular Distributions Linux and Unix Distributions)
Gentoo ebuild
Arch Linux
The Arch Linux wiki has a good article. Read it.
A Ubuntu user has published an install guide as well.
Check Configuring Applications for OSSv4 after you install it.
Overall, I think it's a million times better than ALSA. It's cross platform, and it's stable. It was released a year ago on 15th of March 2007. Since he does not have a marketing department, no one has heard of it.

Hmm, so it's a choice - have to enable effects and use an older mixer, or put up with a 'stuck' progress bar... Well, as I said, I use MOC, and I'm happy with my mixer setup so far, so I'll stick to what I've got.
I can't believe I finally have my headphones working, or external speakers, should I so wish - and what with the ATI divers *finally* providing tear-free video, it's like it's my birthday
Since you mentioned ATI and went offtopic, can you pastebin your ATI xorg? It works fine for me, but If I enable compiz, i get flickering video and slow scrolling. So, I'm stuck with the open source driver, which uses a lot more CPU when I play video.
I can also confirm what the article said about the ALSA OSS emulation. It does work better than ALSA with the ALSA API. xmms with ALSA enabled freezes my sytem. xmms with OSS enabled running ALSA does not. I'm tired of this bollocks. We have to mount a campaign to get OSS back into the kernel.
Anyway, this is my OSS output.

Audio Level Change to and from progr
When I get into even a simple program that i made that didnt go full screen my media player music (WMP ) quieted even though there is now visable change in any audio, also and most importantly is when I load up WC3 or WoW my volume gets lowered on the media player and once again no volume controls change so there is no visable change, I've also had times were there was no sound coming from the player or game, unless I minimised the program and restarted play back in some way but then right when i get back into the game it quits. Sound Blaster Adigy SE?even this simple program that i made changes my audio level soundhttp://thesite.mine.nu:8080/elipse%20test.exeMessage Edited by CTS_AE on 04-20-20072:02 AM
Just to back up Michael. The native sample rate for video is 48khz. To work at anything other than that is to ask for problems.

Drag and Drop audio effect hits all tracks
How is it that when I drag and drop a tried and true compressor effect onto an audio clip (FCP6), it now takes to all audio tracks from the same clip. Then I have to go back and remove the effect from the other (3) tracks. Bug, or setting I'm missing?
ForrestFinal Update: ...god willing...
OK! Check it, like I said in previous posts I seemed to have narrowed it down to specific mp3s not converting and playing in their native sample rate which if paired with another sample would give you the "audio midi sync" error and basically screw up your clock! It appears mp3 files converting to mp3 using iTunes would not convert to the correct sample rate if set to something other than 44 in logic and cause this. A tad peculiar Apple iTunes won't work with Apple Logic. I was able to confirm this on two mac's via my friend in Florida. He's running Tiger and tried the same experiment and Booya! Mickey Mouse! It appears this insane week long adventure has came to an end (...god willing) with a super specific unlucky shot in the dark on my part finally revealed to be an perfectly normal function of Logic (obviously one i'm not fond of..) As far as the errors / crashes / system overloads / kernal panics I think I can sort those out to the mackie onyx satellite not being a good choice and trying to add and remove firewire devices in the middle of the sample rate mayhem. Wow! all I can say is, I'm glad it's over
Wish me a lot of luck in the future.. I'm sure i'll need it! -
High Precision Voltage Source to Calibrate 24 bit ADC
I am trying to find a cost effective way to calibrate a 24 ADC with a voltage source.
The ADC has 3 differential inputs.It ranges from 40, 20, 10, 5, 2, 1, 0.5Vpp
It natively samples at 32 kHz, But I will be taking a 1 second sample as a reading for the calibration.
The source must be able to produce half full scale of each range ie 20V to 0.25V differential.
The source must be able to produce the signal to +-0.01% (ie. 20V +-0.002V to 0.25V+-25mV)
I was looking at the PXI-4132. I will have to buy the PXI frame and controller.
Is there a cheaper or better solution for this task. I also looked at the Keatley $6000 and Agilent solutions $5750.
A SMU appears to be more feature rich then what is called for in this task.
This is my first project please be critical of my post so that I can improve.Two ways: Get a Reference source (have a look at the secondary market like this , I think you will need a recalibration anyway)
or get a stable source and a reference voltmeter.
also have a look how other solved this problem .. like Jim Williams from linear see
http://cds.linear.com/docs/Design%20Note/dsol11.pdf
http://cds.linear.com/docs/Application%20Note/an86f.pdf
However as Lynn already pointed out 16bit seems all you need.
And: Usually an ADC used ratiometric migth go up to 22bit .. not ratiometric it will need a reference better than 22bit (ok 16bit here, that can be done) . So if your ADC will work ratiometric in your application all you need is a stable voltage divider since reference sources are available ....

Since all the factory presets for Space Designer default to "sample rate/2" in a 96k project, I'm assuming the factory impulses are all at 44.1k ?
Any chance there are higher sampling rate versions of these factory impulses hidden somewhere ?
Guessing the answer is "No" ...

I'm pretty sure I remember reading somewhere, maybe the Audio Ease website, that there's really no need to sample reverbs at anything about 48khz, as reverberations rarely contain frequencies over 18khz anyway.
Makes sense. On the other hand, I'm guessing running a 44.1k impulse in a 96k session requires at minimum a realtime sample rate conversion, which will probably degrade the performance of the original impulse.
Not to mention that a 44.1k sample in a 96k session won't necessarily use less CPU... possible that it uses more than a 96k impulse running at the native sample rate. I haven't tried to test.
Probably splitting hairs here, but I'm curious...

Problems with OSS (ALC1200, one speaker only noise)
Hi, im trying to use OSS since a half year, but never got it up running. There is always only noise/scrappy sound on the right front speaker and on the same time on the right Headphone speaker. In OSS test it says ok when testing. Devices are /dev/oss/oss_hdaudio0/pcm0 when this occures the first time, and /dev/oss/oss_hdaudio0/spdout at the second time.
Card is the ALC1200 onboard-chip of the Asus P5Q. Its is recognised by alsa & oss as ALC888, and normally working in alsa.

I tried to turn everything off at record. Oh and this sound is only there when i play sound, not when i do nothing. Any ideas?I'd like to use OSS instead of alsa - just for curiosity and for the rumored "better quality"
I followed wiki and got OSS working, except the same problem as stated above. First I get noise from right front speaker (pcm0) and second from spdout_std (the last one osstest testes). The second last one (spdout) gives good sound though, so I could symlink /dev/dsp to /dev/oss/oss_hdaudio0/spdout, but then how to get sound out from the optical SPDIFF output?
Has anybody solved this yet, or do I have to go back ALSA? -
Audio clips change when moved from sequence to sequence in FCP7
Working on a documentary piece within FCP7 and am having problems with moving audio from one sequence to another. Both sequences have the same settings, but when I copy the audio clip and paste it into the new sequence, the audio that pastes is from the same clip but is not what I copied. Does anyone know why this is happening and/or how to fix this?
Just to back up Michael. The native sample rate for video is 48khz. To work at anything other than that is to ask for problems.

Need help interpreting JRA recording
I'm troubleshooting some out of memory issues and using jra recordings for several months now, but after reading up on the topic specific help in Mission Control, I still have questions. I hope someone with a little time can answer some of these or point to a resource which has some detailed info.
The screenshots below are during a period when a WebLogic 8.1.6 server is basically out of memory (2GB heap). It doesn't throw an out-of-memory error, but it continually garbage collects tiny pieces of memory although never enough to get real work done so it appears to the user as 'frozen'.
Here is the 'General' tab.
!http://i44.tinypic.com/5u4f4m.png!
#1) This shows 712 page faults during this 30 second interval. What is a page fault in this context? When I think of page fault, I think of going to a page file on disk which I wouldn't expect since the heap should be all in memory.
#2) Is there a way to figure out what the exceptions are? They aren't high enough to be disturbing here, but I've seen values as high as 1000 per second (30k in a 30 seconds) in my recordings recently.
Here is the 'Heap' tab.
!http://i39.tinypic.com/k4jihc.png!
#3) The first thing I notice is 2.00 GB committed and 2.07 GB large objects (values at top of screen). The objects add up to a larger amount than the heap. Is this just rounding errors?
#4) Free memory table shows -95 MB free on the left side and +6.8 MB free on the right side (distribution).
The 'Methods' tab.
!http://i41.tinypic.com/16kisz.png!
#5) I often see all but a small handful of samples in the FastSystemCallRet method. Is there a way to force more samples so I can see a better sample across my own methods?
The 'Objects' tab.
!http://i44.tinypic.com/bf3tsk.png!
#6) This is usually the first place I go to see how all the memory is being spent. Often I see one of my objects in there somewhere to tip me off on what is holding too much memory. In this case, however, everything just looks like strings, chars, and bytes. Is there a way (now or in a future release) to roll up these simple data types into the object referencing them? Strings, bytes, chars, and hashmaps are so fundamental that it is difficult to tell what objects are holding them.
#7) The 'Heap' tab over 2 GB of heap in use. Adding the total size of the objects on this page only accounts for 80% of the memory. I guess that means 20% of the memory is used by objects that are smaller than 11 MB (.054% of 2 GB). Is there a way for me to set the threshold to a lower value (like .005%). I'm really not as interested in the total size of those little objects as I am the number of instances (since each instance probably hold some strings, chars, bytes, etc).
Thanks for your help.
BillHi Bill,
I will try to answer your questions in order...
1. Also newly allocated native memory will be reported as page faults when committed. So if there is a GC which uses a bit more native memory that already in use, for example during compaction, it will allocate this and will then generate "page faults".
2. Yes there is.
1000 exceptions/s is worth to reflect over, but may not be an issue at all.
It is worth to be more worried if they are hardware exceptions (for example a NullPointerException) since they will be more expensive due to the transition into kernel. An exception that is caught directly and not using the stack trace is the cheapest of all exceptions...
A way to get which exceptions are thrown can be found with verbose flags. I then recommend to start the application and start gathering the info in running mode using jrcmd.
Example that prints most exceptions:
jrcmd <pid> verbosity set=exceptions=INFO
Example that prints most exceptions including stacktraces:
jrcmd <pid> verbosity set=exceptions=DEBUG
Example that prints all exceptions including stacktraces:
jrcmd <pid> verbosity set=exceptions=TRACE
(This level will also include ClassNotFoundException and others which are thrown during class loading, but you likely don't look for)
3, 4. This looks weird and need to be investigated further.
I will have to say pass on this one.
5. As a first step, I recommend you not to include native samples. Native samples does include idle time and does therefore skew the profile.
You can also increase the sample rate, which will give you more samples. It should by default be every 5:th millisecond.
Looking at the profile you will see the methods as they are generated by the JVM. This means that if a method is small and inlined, it will not show as a method of it's own, but with a sample in the outer method. This gives you a correct view of where the application is spending time, based on how the application is optimized, but a bit complex.
It can be useful to disable optimization to get a more fine grained profile (knowing it may be different). That is done with the jvm option -Xnoopt.
6. Interesting request. I have heard it before and we have discussed how to group things together for a better view of the application.
What you can do is to connect with the memory leak tool. Then you will be able to walk the heap and look at what is there. For example you could look at which the larges HashTables are by viewing the HashTable$EntryArrays and sort on size and click the largest one you want to inspect. You can then follow the references back and see who is holding on to it, to give an hint on why.
7. The value shown in JRA is not the actual cut-off, but how large part the group of objects occupy.
You can also use the request JRA does with the diagnostics command "print_object_summary".
There it is possible to set the threshold, example:
jrcmd <pid> print_object_summary cutoff=0
It is possible to invoke diagnostic commands download JRMC 3.1 (available on OTN) you can invoke diagnostics command via the management console, so you do not have to be on the machine in that case.
I do not know which GC you use, but if you use a generational one (with nursery), the nursery would also be part of the heap and an old space collection would be triggered in order to make room for it when old space is full. But if the nursery size isn't fixed, it should shrink, possibly it has. It is a factor to include in heap sizing.
Best regards,
Stefan -

hope somebody can help meNo you can dump alsa and just give a command to run Doom 3. Doom3 was built on using OSS, so its not a proble. It normally detects OSS. To be sure it does run:
doom3 +set s_driver oss
A link:

with a bit-more. Not sure if doom uses openal, but I had to once reinstall openal to get it to detect oss.

AppleTV and lossless DTS CD rips
The new AppleTV appears to resample everything to 48Khz so apple lossless rips of DTS CD's no longer work as they require a 44.1Khz pass through to the receiver in order to be properly decoded. Just a heads up to anyone who may depend on that capability.
The ideal would be for the AppleTV to pass things through in their native sample rate, which would even allow for higher quality Apple Lossless playback at 24/96, etc.
I wonder what the options are for multichannel storage/playback now with iTunes and an AppleTV?Wow, this is not good. I'm quite suprirsed that Apple does not allow for bitperfect output. Very bad.
BTW, if it does pass 5.1, as it does sometimes, do we know if it still resamples the TOSlink? Has anyone gotten 5.1 through the optical port? [I know this isn't dealing with music itself, but this might speak to whether or not Apple is making choices about resampling or not in software.]
A Macworld article, I think it was, mentioned that only certain 5.1 sources would make it through without being output as PLII.
