Removing 'Digital' Sound

    I recently recorded some speech with the line-input on my MP3 player at 96KHz which I thought would be adequate and when I play it back, it sounds 'Digital'.

    It's as if the speech has been passed through a flanger?!

    I was wondering if there is a way to remove this 'Digital' sound from the speech in Adobe Audition?

    Is it impossible for you to re-record with something better than an mp3 player?

    If not, maybe try some careful notching in the upper bands to tame that wobbly mess a little bit.

    good luck

    Unfortunately, I cannot re-record the speech. :(

    I would have thought that 96Kbps would have been fine for speech?

    There are also options to record in 112Kbps (MP3), 128Kbps (MP3) and 32KHz (WAV), 16KHz (WAV), 11KHz (WAV), 8KHz (WAV).

    I was using a line-out feed from a mixer and not the internal microphone.

    Saemskin, what frequencies should I try to notch out?

    Re: AUD10

    Post a sample snippet and we may get somewhere.
    Ultimately, I only *think* I know what phenomenon you are referring to, but without hearing it, I would of course just be stabbing in the dark.

    get a sample up and we'll go from there. :cool:

    Ah, I'll bet it's the "mp3 jingle." I hate the mp3 jingle. 96kbps should be sufficient for a voice recording--heck, even lower can be OK depending on your expectations--but a poor mp3 encode can cause the jingle at almost any bit rate. It might just be your recorder. Do things sound OK when you record other stuff at higher bit rates?

    Like dude was saying, I would try just filtering out everything above like 10K or 12K. Might reduce some of the audible jingling without harming the main vocal range.
