Thread: Digital destortion of tracks when ripping into 16/44 KHZ mono

    Digital destortion of tracks when ripping into 16/44 KHZ mono

    Hello there

    Reasontly, a strange issue has arisen, and I cant quite find out how to fix it.

    I have reasontly purchased some audio CD's containing old BBC radio material. I am in the process of ripping these onto my harddrive, however, as this is only mono-stuff from the 40'es I am using the DSP setting to make the channel count into 1, so that I am ripping in mono, and thereby saving space on my harddrive.
    The only thing I am changing in the dsp action menue is the channel count, and nothing else. Now the strange thing is happening. Whenever this setting is on, I am getting slight destortion on my tracks, just as when to much normalization has been added to a file and clipping is acurring. Whenever I am removing the DSP setting, all is fine, and the tracks ripps ok.

    I have tried with 2 diffrent drives, but everything is the same. I have of course also checked that I have not accidentily added the volume normalize feature from the DSP settings menue, however I havent.

    Does anyone has an idea of what is going on here?

    All the best from Allan

    Redbook audio CDs always contain 2 channels of audio, even if the audio is mono, so when you rip the CD, CD Ripper is summing 2 mono channels to 1 channel, hence the distortion.

    Try using the Channel Mapper DSP.

    Thanks for your swift reply. It does make sense, and to be honest I hadnt thaught about that being the case, especially not as I have ripped alot of other mono-titles before using the channel count=1 DSP and experienced no destortion. This is the first time this has happened to me.

    Can you please elaborate a bit on how to use the channel mapper correctly?

    All the best from Allan

    Try clicking the help button in the Channel Mapper DSP settings.

    In short, use channel mapper, 1 channel, set Channel 1 from channel 1 (0dB, 100%)

    Spoon, I recently ripped the Beatles Mono CD box set. Should I have used this channel mapper or is it “safe” to just use the DBPA default settings?

    many thanks!
