    Good to know. I'll take a look at what they are calling a permissions problem tomorrow. I think brutefirwrapper is lacking executable permissions.

    The lights on the ethernet socket are flashing away, but I simply cannot find it.

    In what ways could it be broken?
    Have you tried power-cycling it. ie. pull the power and plug it back in?

    BrutefirDRC on CSOS

    Hi JackOfAll,

    It is my first post in CSOS forum. I appreciate your great work on Community Squeeze project!
    Here is my painful way to make BrutefirDRC working on CSOS. I am more acoustic then Linux guy,
    so please check if there are any errors in my thinking logic writting attached instructions.


    1.

    Install BrutefirDRC:

    Code:
    sudo csos-cleanInstall logitechmediaserver-plugin-BrutefirDRC

    2.

    Add Samba share folder:

    Code:
    sudo nano /etc/samba/smb.conf

    Code:
    ## add  BrutefirDRC samba shared directory ##
    
    [BrutefirDRC]
    comment = Read/Write file share
    path = /etc/squeezeboxserver/BrutefirDrc
    guest ok = yes
    writeable = yes
    create mask = 0777

    3.

    Make directories used by BrutefirDRC writtable.

    Code:
    sudo chmod -R 777 /etc/squeezeboxserver
    sudo chmod -R 777 /usr/share/squeezeboxserver/Plugins/BrutefirDrc
    4.

    Go to Samba share folder "BrutefirDRC" from your PC and add required filters in /filters folder.


    Each filter for given frequency consist from 3 parts:

    Filter_44100.txt
    Filter_44100_Left.pcm
    Filter_44100_Right.pcm

    They reside in folder /etc/squeezeboxserver/BrutefirDrc/filters/

    Examples of working filters can be found @ sourceforge.net/projects/brutefirdrc/files/brutefirdrc/4.1.beta/filter_examples_4.1.beta.tar.gz/download

    You need to edit sample .txt files to use your .pcm left and right filters!

    5.

    Having more popular filter format like: Filter_44100_stereo_32bit.wav (generated from awesome program Rephase 9.7)
    You can use sox conversion to obtain .pcm filters
    Just place Filter_44100_stereo_32bit.wav in folder /etc/squeezeboxserver/BrutefirDrc/filters/
    and use code:


    Code:
    sox -t wav /etc/squeezeboxserver/BrutefirDrc/filters/Filter_44100_stereo_32bit.wav -e floating-point -t raw /etc/squeezeboxserver/BrutefirDrc/filters/Filter_44100_Left.pcm remix 1
    
    sox -t wav /etc/squeezeboxserver/BrutefirDrc/filters/Filter_44100_stereo_32bit.wav -e floating-point -t raw /etc/squeezeboxserver/BrutefirDrc/filters/Filter_44100_Right.pcm remix 2
    6.

    From LMS player menu choose your "Player" and "BruteFir Room Corection" submenu.
    Choose for example Flac, then Filter_44100.txt


    7.

    From LMS settings menu choose advanced/file types and make sure that your Flac conversion is executed by sox/Brutefirwrapper only.


    8.

    Play some flac files...

    9.
    Go to:

    Code:
    sudo nano /var/log/squeezeboxserver/brutefir.log
    to check for possible error massages.

    Here is my painful way to make BrutefirDRC working on CSOS. I am more acoustic then Linux guy,
    so please check if there are any errors in my thinking logic writting attached instructions.
    Welcome and thank you! At last someone has actually tested brutefir on the Wandboard. I expected to see much higher CPU usage, so that's good! I'll take a look at how it is packaged later today and maybe include a sample filter in the package.

    Would you say that the WB responds quickly with this load, for example when seeking or switching tracks in LMS?

    As I recall it, the future CSP hardware aims to bypass the DAC chip's internal filters, so that JohnSwenson's filters can be used instead. The internal filters are only bypassed at the highest sampling rates; 352.8 and 384 kHz. Again, as I recall it. Would it be possible for you to test these sampling rates? If so, does the WB respond quickly then?

    Does anyone remember if JohnSwenson's filters are/will be implemented in hw or sw (probably)? If in sw (SoX?), does anyone know how it affects the performance? In other words; would this be possible to run at the highest sampling rate, at the same time as using BrutefirDRC, in terms of performance? Is the WB that powerful? (I hope so!)

    DSD loose ends....

    Any of you guys using Touch USB out (with EDO plugin), to output to a DoP capable DAC? If yes, can you test the PlayDSD plugin, that allows you to specify DoP/PCM output from the LMS web-gui. (Settings->Player->PlayDSD).

    Make sure you are on LMS 7.9...
    Code:
    sudo csos-cleanUpdate-unstable logitechmediaserver\*
    Install the PlayDSD plugin...
    Code:
    sudo csos-cleanInstall-unstable logitechmediaserver-plugin-PlayDSD

    We're not using a JS designed filter. Using the SoX Resample library (libsoxr).

    I expect it's not going to be a problem. I typically see CPU usage of 30% (a single core) using soxr to upsample to 384k. Based on the brutefir numbers posted above, I don't believe "horsepower" is going to be a problem, combining them. (Gut feeling, rather than tested fact. I've got too much on my plate to say I'll verify this. I'd rather hope that the people who want to use it would test it. )
