Using ClickRepair

  • Using ClickRepair
    A weekend project

    ClickRepair is a mature, well-tested, application for de-clicking and de-crackling audio in uncompressed audio files. It has been developed over a period of many years.

    What you need for this project:
    1. Audacity -Audio transferring software (free for PC and Mac)
    2. Demo (or paid version) of ClickRepair (for PC or Mac)
    3. Turntable connected to computer (or) raw audio file in .wav format to use in Audacity

    (If you need an audio file, download our test file here which will help you...)
    >> Download File Right click on this link and save to your computer's hard-drive (HMV., BD.761 (OER.458) Kentucky Minstrels - "Bless This House")

    STEP 1
    Have your turntable setup and switched on, with a 78rpm record ready to be transferred. This will streamline the process.
    Open Audacity program on your computer's desktop:

    Either import our raw test 78rpm file into Audacity to use or begin transferring your 78rpm using your turntable and the Audacity software. Depending on your turntable configuration, you may need to adjust your volume settings or input settings - but Audacity makes the process simple and hassle free. When you're ready to record your 78, click the record button on Audacity and wait until the recording is complete.

    When complete, save your raw file in .WAV format by clicking > FILE > EXPORT on the Audacity menu.

    Save the file to your desktop or selected folder. Now, open the ClickRepair program...

    STEP 2
    In order to "process" your raw audio file, you'll need to import it into the ClickRepair software. This is done by clicking the OPEN button on the main window of ClickRepair and locating your raw file on your computer's hard-drive like so:

    Once you've selected it, you'll also be prompted to locate where you want your processed file stored as well as what the finished file will be named. (The software usually prompts the user to save the file with an additional "-cr" suffix. This is helpful when needing to locate the raw and modified files...)

    When ready, click the start button on the ClickRepair software to begin the de-clicking/de-crackling process.

    When it comes to deciding how much or how little processing you want with your file, it's a matter of preference or tolerance. If the disc is heavily scratched or damaged, you may need to increase the level of de-clicking and/or de-crackling using the slider bars at the bottom of the ClickRepair window. In the screenshot above, these settings are at 80% and 90% respectively. These settings will give very good results - but the overall end result will depend on your keen listening skills. If you set the DETECTION and REVIEW setting to "DEFAULT" (on the drop-down menu), this may be a good starting point for the novice. As you transfer further 78rpms, you will begin to "find" the "correct" settings for each recording...

    Tom Jardine I use ClickRepair all the time. It's wonderful for removing most record noise. It does great on removing crackle from British HMV's, Decca's, etc. leaving a background hiss. The software includes ClickRepair RT (real time), DeNoise and a DeNoise that remo...  more

    Tom Jardine Another worthwhile hint mentioned in the ClickRepair manual, make your transfers of mono records in 2 channel stereo. This enables ClickRepair to remove noise on BOTH channels (left and right sides of the grooves) and then combine to one channel monaural.
