    Default Sony STR-DN1040 - Stream FLAC instead of MP3??? - SOLVED

    Could a profile for a Sony STR-DN1040 network enabled receiver be created that streams the media as lossless FLAC instead of lossy MP3?

    I don't know about the other receivers in the STR lineup, but the STR-DN1040 supports FLAC at 8 kHz-192 kHz, 16 bit & 44.1 kHz-192 kHz, 24 bit.

    I have been able to play 44.1 kHz and 48 kHz, 16 bit files native if I disable the transcoding function for the receiver in Mezzmo. I have 500+ CD's that were ripped on a Home Theater PC in a WMA Lossless format and I really don't want to have to re-encode them all. I was hoping Mezzmo would be able to transcode them to FLAC as they are played.

    From a music quality point of view, I would think it would be better to use a lossless format as opposed to a lossy format.

    Thanks for any reply,

    Steve.


    P.S. If FLAC has been troublesome in the past then what about WAV???

    Hi Steve,

    We can certainly create the device profile. Email us a few things:

    • Turn on logging and restart your Mezzmo server. Connect to Mezzmo from your Sony STR and browse and play a few files. Then, stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.
    • In your email, also provide the video formats, music formats, photo formats & subtitle formats that the device supports. Include as much information as you can gather (e.g. formats, bitrates, sample rates, channels, etc.)

    Should I turn the transcoding back on in Mezzmo for the receiver and then play the files (Mezzmo converts WMA Lossless to MP3 and sends MP3 format to receiver)? Or should I leave transcoding for the receiver turned off and play the FLAC files? Or both - different sets of logs of course.

    The "Sony STR" profile is the correct profile for this receiver (Sony STR-DN1040 AV Receiver), right???

    As far as formats supported that's easy. This receiver only supports audio playback from network, USB & Bluetooth sources. It does not support video or picture playback from network, USB or Bluetooth sources.

    The manual says it supports the following formats-
    MP3 (MPEG 1 Audio Layer-3):
    32 kbps – 320 kbps, VBR

    AAC:
    16 kbps – 320 kbps, CBR, VBR

    WMA9 Standard:

    40 kbps – 320 kbps, CBR, VBR

    WAV:

    8 kHz – 192 kHz, 16 bit PCM

    8 kHz – 192 kHz, 24 bit PCM

    FLAC:
    8 kHz – 192 kHz, 16 bit FLAC
    44.1 kHz – 192 kHz, 24 bit FLAC


    I am interested in the FLAC support as the source files are WMA Lossless and the FLAC format is also Lossless, WAV would also work if FLAC has proven to be problematic in the past.

    I do know the source files are WMA Lossless 44.1 kHz 16 bit.

    Thanks again,

    Steve

    Thanks for the information. Select the 'Sony STR' device profile and turn transcoding on. Turn logging on in Mezzmo and then restart your Mezzmo server. Connect to Mezzmo from your Sony STR and browse and play a few files. Then stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.

    Three files played, WMA Lossless, MP3 and FLAC.
    All files were transcoded to MP3 (or passed through as) by mezzmo and sent to the receiver.

    Log files sent.

    Thanks,

    Steve

    Paul,

    The new profile works GREAT for the 3 music formats that I have. The WMA Lossless played as FLAC, the MP3 played as MP3 and the FLAC played as FLAC. Thanks again for doing this!!!!

    Steve


    EDIT - Do you know what parameters the WMA Lossless files are transcoded to FLAC as, or is it the same as the original WMA Lossless file, i.e. WMA Lossless 44.1 kHz 16bit transcoded as 44.1 kHz 16bit FLAC.

    The STR-DN1040 does not show bit information for a FLAC file, only that it is playing a FLAC file. It doesn't seem to be having any problems with the WMA Lossless to FLAC transcodes provided by Mezzmo.

    Glad that works well, Steve. Your WMA Lossless files will be transcoded to FLAC with matching (or very similar) bitrates & samplerates.

    Just an update to others that may come across this thread looking for information. After doing more testing with audio quality (perceived or actual) and tweaks to the profile by Paul ( Thank you Very Much!!) the profile for the Sony STR-DN1040 receiver (STR-2013) has been tweaked to transcode WMA Lossless to WAV instead of FLAC. This new profile was first introduced in Mezzmo version 3.3.1.0.

    Good news also was despite the manual saying this receiver supports AAC files 16kbps - 320kbps I had no problem playing back 512kbps CBR files native through Mezzmo.

    Hi Paul,

    I am having exacly the same problem, yet I am not figuring out how you managed to get it to work. I can see two different profiles in Mezzmo, one "Sony STR" and one "Sony STR 2013" now wich one is the correct one to use in order to be able to play FLAC files. I have tried both and when using "Sony STR" Flac format is converted to MP3, when I use "Sony STR 2013" it does play FLAC as FLAC, but when trying to play a 32bit - 96kHz FLAC file it does not want to play. I have tried to convert the FLAC file down to 24bit and 16bit, but still nothing. so I could say that for me it is partly working.

    Is it possible that I need to change some other settings that are not mentiond in this thred?
