Thread: Very Slow Encoding Speed

  1. #1

    Very Slow Encoding Speed

    Hi there,

    I have just started using the dCW to burn my flac files to CD.

    However this process seems VERY slow. It encodes at only 4x.

    I have an Intel Q6600 CPU with 8GB ram. When using the CD ripper and other db products it encodes MUCH quicker.

    EDIT: When I convert from FLAC to WAV using dbConverter (which is I assume what the cdWriter is doing?) I get an encoding speed of around 160x

    Is there a setting somewhere I am missing?

    Thanks
    Paul

    The actual CD writing is dependant on CD writer drive speed.

    It's not the writing speed that is slow, but the encoding speed when it converts from flac to wav in preparation for burning.

    The frequency of the source file is 44.1KHz and 16 bit 2 channel?

    Yep. Just a standard FLAC file made from a CD.

    In DbPoweramp Converter the same file encodes to .wav at around 140x

    Also, when using the CDWriter to encode the flacs...CPU utilization is very low. Around 3%

    Sorry I have no idea why it is running slow on your system.

    Same problem. I have Reference Version 14 and an Asus G73Jh quad core w lots of memory. Very fast on encoding to FLAC. All 8 cores used. Desperately slow going from FLAC to audio (not data) CD. Nero does it in 2 minutes or less.

    +1 - Same problem. CPU usage on my Q6600 stuck at ~4%, with antivirus disabled. Can't seem to work this one out... :confused:

    I have this same problem since upgrading to R14. If I am lucky it will encode at 2x. Unusable!

    Previously you were using which version (which presumably was fast)?

    Re: Very Slow Encoding Speed

    Sorry to double-post (previously posted under CW Writer v3.2 beta release thread), but this is the same problem I was reporting there... Namely, I'm running CD Writer R3.2 on Windows 7 Professional SP1 with the 18-MAR-2011 release of dBpoweramp R14.1 beta, and it's taking a long (longer than normal conversions) to convert files to the temporary format (wav?) needed by CD Writer... it's using almost no CPU on a i5 with 2 cores (4 with hyper-threading), and taking 30ish seconds (about the time taken to encode an entire 20-25 track album, let alone two tracks) to transcode two mp3s ?!

    Screenshot here

    Also two questions... when erasing CD-RWs, will you be adding the option to quick erase as well as current default of full erase? And am I right in presuming that CD-TEXT is still not supported?

    Thanks,
    -Peter

    It is not currently planned to add these
