How to enable "production quality with extra precision"?

[tarik2cyprian]

How would I enable "production quality with extra precision" on ubuntu 12.04? I understand that you have it working on Arch.

I only have fast, high and off in the v-mix under the most recent Oss4.

How would I enable "production quality with extra precision" on ubuntu 12.04? I understand that you have it working on Arch.

I only have fast, high and off in the v-mix under the most recent Oss4.

The "production quality with extra precision" somehow disappeared, and it was said that it did not exist.
What is available is the Russian "exact scientific resampler" (you may find it in this thread).

Although the "production quality with extra precision" ceased to exist, the crappy "production quality" can still be enabled. This was already explained by Cesium in this thread.
You may also want to read a manual on how to compile OSS4 from Mercurial https://help.ubuntu.com/community/OpenS ... rom_Source

In a word, it is very probable that you do not need that "production quality". What is your "ossinfo -v9"?

I know it is something you have to modify in the scripts of those audio programs but I don't know how.

I know it is something you have to modify in the scripts of those audio programs but I don't know how.

According to your "ossinfo -v9", the OSS4 driver for your Xonar supports a wide range of sample rates: 32000 - 192000 (Hz). This means that almost all sound files (except for DXD Waves and other super HiRes) can be played without sample rate conversion. Thus, OSS4 resamplers can be disabled. However, the driver does not support 24bit format.

An optimal configurations of the OSS4 mixer might be:

Code: Select all

$ ossmix
vmix0-enable ON|OFF (currently ON)
vmix0-src <Fast|High|High+|Production|OFF> (currently OFF)

This means that vmix is enabled, but vmix0-src (sample rate conversion) is disabled.
The format conversion is still enabled. I tend to use this configuration on my notebook with Intel HDA codec.

This configuration is preferable for playing HD video files, because it minimizes processor load. Everything else seems to work without problems (Skype, etc.) The only trouble-maker is Flash player. It can hijack the sound device, and other application would not be able to play sound. In this case, you can simply close a web page with Flash, or close your web browser. Another notorious trouble-maker is KDE notifier (it can be disabled in KDE preferences).

For playing HiRes FLACs you may want to install Petrov's plugins for Deadbeef and Audacious. They can be obtained by e-mail from Sergey Petrov (it is supposed that you have already tried his resampler).

Petrov's plugin for Deadbeef is easy to install. Just copy it to the Deadbeef folder:

Code: Select all

$ ls
oss_rate-i386.so 
oss_rate-x86_64.so
$ sudo cp oss_rate-i386.so /usr/lib/deadbeef/oss_rate.so

(Warning: it might be another folder on Ubuntu, a sort of "/usr/local/lib/deadbeef" or something else.)

Then you start Deadbeef, go to the preferences, enable Petrov's plugin and configure it (enable "exclusive" mode, select the sample rate you need, and so on). You may want to start deadbeef on terminal to see all info about playback. It might be helpful for troubleshooting. It might also be interesting, if you are playing surround sound.

Notice that the open source OSS4 plugin for Audacious (git-version) supports "exclusive mode", which can be enabled in "preferences".

Petrov's plugin for Audacious is the so-called "effect plugin", you can find it in "effects", if it is installed. It can be installed in a similar way:

Code: Select all

$ ls
fftrate-i386.so 
fftrate-x86_64.so
$ sudo cp fftrate-i386.so /usr/lib/audacious/Effect/fftrate.so

It might be another folder on Ubuntu.

If you have questions about Audacious/OSS4 sound quality settings, you may contact Michal viewtopic.php?f=3&t=3834&p=15221#p15221 He may also help with Petrov's plugins.

Thanks once again Igor for this great info,

I believe my sound card can play 24 bit. I will have to give it a try and find out. I also noticed that flash is also buggy unless you close the webbrowser.

Do you happen to know what Petrov's email or contact information is so I can uptain the plugins? You can send it to me via pm if you want.

Thanks once again

[igorzwx]

I believe my sound card can play 24 bit. I will have to give it a try and find out.

Your soundcard might be able to play 24bit format, but the OSS4 driver for your soundcard does not seem to support such format. You may ask developers to fix this problem. Moreover, this driver is "beta", it might be buggy, it may also fail to play 192kHz sample rate.

Do you happen to know what Petrov's email or contact information is so I can uptain the plugins?

Try the resampler. It can be downloaded here: viewtopic.php?f=3&t=3543&start=45#p15974

[tarik2cyprian]

Does anyone have a copy of Petrov's Exact Resampler plugins for Deadbeef. I have been contacting him since January up till now but he
never responds to any of my emails to provide me with this plugin.

Does he have new email address which I can contact him?

Or can somebody else provide me with this plugin for Deadbeef and send it to me via pm or my email address
which is iq4boogle@gmail.com.

Any help will be greatly appreciated

Igorzwx,

I just wanted to say thank you so much for updating this thread for Petrov's Exact Resampler plugins for Deadbeef along with the other info. The last
time when I responed to this thread and you replied I did not see that info with the attached Exact Resampler plugins.

Thanks once again Igorzwx,

Doese anyone have a plugin for deadbeef called a delta noise sharping plugin.

The file would be called dlta.so. If someone has this plugin or where I could find it would
be great.

There is a "git", which is easy to find with Google. Keywords: "dlta.so deadbeef"
You have to compile it from the source.

If the code is too old, it may not work with the current version of DeadBeef.
In this case, you may try to contact the developer.

[ossuserr]

Greetings, Igor. Where can i take source code of Petrov's resampler? Also which sound card would you recommend for professional use with oss driver? I could only find 32-bit deb file but i need source code to compile 64-bit.

[igorzwx]

Where can i take source code of Petrov's resampler?

Both Petrov's resampler and Petrov's plugin for DeadBeef player are "closed source".

which sound card would you recommend for professional use with oss driver?

For "professional use", you may need a sort of "professional audio device". Right?
You may try a kind of LynxTwo soundcards _http://manuals.opensound.com/usersguide/lynxtwo.html
They are said to be "professional".
NOTE: It makes sense to search the forum for "LynxTwo" to find out which of LynxTwo cards work with OSS4.

The "closed source" driver for LynxTwo is here: _http://www.opensound.com/download.cgi

I could only find 32-bit deb file, but i need source code to compile 64-bit.

OSS4 can be compiled from git:

_http://www.opensound.com/
OSS v4.2 build 2010 for Linux, Solaris, FreeBSD and UnixWare announced.
Browse the Open Sound Git Repository
Get the source code using GIT:

Code: Select all

git clone git://opensound.git.sourceforge.net/gitroot/opensound/opensound

If you have problems with "git", you may ask for help on Gentoo forum.

Notice that all your questions are off-topic.
You may better start a new thread for each of them.

1 What's the point to keep Petrov's driver closed source?
2 By 32-bit i meant the fttrate Petrov's plugin in deb form. And since there is no open source for it we can't compile it to use instead of samplerate in alsa. Can Petrov provide 64bit of fftrate?
3 Lynx is too expensive. I meant some cheap cards like M-audio or esi juli level.

[igorzwx]

Can Petrov provide 64bit of fftrate?

It was already provided (in this thread), and it was downloaded 651 times.

Lynx is too expensive. I meant some cheap cards like M-audio or esi juli level.
