    Re: xHE-AAC

    I confess that I could not warm to EAC but I knew that you were a big user . As for fdkaac.exe my memory was finally jogged and if you ever want to go a little deeper into the rabbit hole I have published a page a while back demonstrating how to cross compile fdkaac for Windows on a linux platform using MXE. The distro used is actually Slackware but the principles would be the same for Ubuntu:

    https://www.andrews-corner.org/mxe.html

    This way you can 'roll your own' without waiting for somebody to provide an updated copy. Mind you Slackware makes it all very easy...
    You think that's air you're breathing now?

    Re: xHE-AAC

    thanx will definitely try this


    PS i do use slackware on my older machine too and worship it but Ubuntu still on my main and will try on U


    EDIT


    tried the guide on MXE on Ubuntu and rolled my own fdkaac.exe 32 bit for my EAC [tried stupidly 20 times with the downloaded one only to finally realize it was a 64-bit der!]
    AS all your guides worked a treat
    Thanx



    on EAC

    Code:
    -p 29 -b 39 -a
    gives you a


    Code:
    Writing application                      : fdkaac 1.0.0, libfdk-aac 4.0.0, CBR 38kbps
    
    Audio
    ID                                       : 1
    Format                                   : AAC LC SBR PS
    Format/Info                              : Advanced Audio Codec Low Complexity with Spectral Band Replication and Parametric Stereo
    Commercial name                          : HE-AACv2
    happy with that

    That is excellent news . My colleagues on HydrogenAudio have demonstrated that binaries compiled as native Windows applications using Windows compilers tend to be a little faster than the binaries produced by MXE from a native Linux host. But there is a greater joy in rolling your own Windows executables for sure, rather than trustingly downloading somebody else's efforts, and MXE can be a lot of fun!

    Good to hear that EAC is firing ahead with your fdkaac.exe, you certainly are the source of knowledge on EAC running on Linux. There appears to still be audio CDs and interest in them in places, it will be sad when this technology has slowly faded away. My own investment of time and effort in audio CDs has decreased somewhat but I have recently purchased a USB3 external DVD burner so that I can experiment a little with exhale and abcde. Not out of the box yet but next rainy weekend I will start at it.

    And as an aside: it is good to talk to you again! UbuntuForums seems to have subsided a little from busier days but it is nice to 'see' old friends again

    Totally. Not sure what happened. It all went dead[-ish] at one point. Was more vibrant a few years ago it seems

    Thanx for all the tips Andrew

    PS and yes under Wine all these currently active

    Re: xHE-AAC

    I have just now updated the xHE-AAC patch to cover the latest git abcde and tested it all out and it ran very, very nicely! Also I have added an ~/.abcde.conf file for xHE-AAC:

    ~/.abcde.conf for AAC: Exhale
    https://www.andrews-corner.org/abcde...ac.html#exhale

    My colleagues on hydrogenaudio tell me that playback under Linux is possible with RhythmBox if gstreamer plugin is compiled against fdkaac. I have not tried this as I am not really a GStreamer sort of guy, still waiting for FFmpeg to come to the party.

    I am aware that my enthusiasm for exhale and xHE-AAC encoding is not widespread, but I still feel that it is so exciting to get in at the beginning with Open Source xHE-AAC encoding .

    Interestingly enough it looks like the next version of Ubuntu has already done this:

    https://packages.ubuntu.com/hirsute/gstreamer1.0-fdkaac

    Re: xHE-AAC

    Oh no not there yet .... what am i to do with the patch? I probably did not understand what it is i should do with it Andrew


    this is what i did
    Code:
    sudo chmod +x abcde_USAC.diff
    then
    Code:
    sudo mv abcde_USAC.diff /usr/bin
    clearly not the right thing to do .... do i need to copy parts of the patch into /usr/bin/abcde ... that does not seem right either .... please kindly enlighten

    my version of abcde is abcde v2.9.4-DEV.

    Re: xHE-AAC

    If you modified abcde before (by patching for exhale) there is nothing more required, the newer patch does not add anything different than the previous patch, just lines are changed to follow git head.

    If you are using the latest version of exhale you might want to experiment with the newer presets:

    Code:
     preset	=  # (0-9)  low-complexity standard compliant xHE-AAC at 16*#+48 kbit/s
     	     (a-g)  low-complexity compliant xHE-AAC with SBR at 12*#+36 kbit/s
    I have not looked at the SBR options yet. Neither have a I looked at the options for LUFS and dBFS in part because I have no idea what these options even mean
    You think that's air you're breathing now?
