This guide assumes you are running Windows. This guide also assumes you are planning to burn the files to a CD as MP3 files on a data disc, or are converting for your portable device in case your device does not recognize the fileset with 48khz sample rate, or are burning WAV files on an audio disc. If you are simply going to be listening to the files on your computer, there is no need to convert a 48khz fileset to 44.1khz.

Prerequisites

You will need:

Installing

  1. Install foobar2000. The default settings are sufficient, just advance through the pages. Also install the encoder pack.
  2. Extract LAME to somewhere you'll remember it, for example, a subfolder called "LAME" in your music directory.
  3. Open foobar2000.
  4. Go to File -> Preferences -> "Components" tab.
    • Click "Install..."
    • Find the foo_dsp_resampler_0.8.3.zip file and select it, then click "Open".
    • Click "Accept" on the dialog box that pops up.
    • Click "OK", then "OK "again.

Converting to MP3 format

  1. Drag and drop the files you wish to convert into foobar2000.
    • If the tracks are not already selected, select them all.
  2. Right click anywhere in the selected area.
  3. Mouse over "Convert", then click "..."
    1. Click "Output format".
    2. From the list, select "MP3 (LAME)". Click "Edit".
    3. Drag the slider to the left until it says "~190kbps (*), V2". This setting results in files which are significantly smaller than the original, yet should sound the same as the lossless (FLAC) files.
    4. Click "OK", then click "Back".
  4. Click "Processing".
    • Scroll to the right under the "Available DSPs" box and double click on "Resampler (SoX)".
    • Click on "Configure selected".
    • In the dialog box, click the dropdown box next to "Quality" and select "Best". Click "OK".
    • Click "Back".
  5. Click "Convert".
    1. When asked to locate LAME, browse to the directory you extracted LAME to in step 2 and click OK.
    2. When asked to pick a directory to place the converted files in, create a directory and double click it, then click OK.
    3. Wait for the files to finish converting. This may take several minutes depending on your computer's speed, and how long the recording being converted is.
  6. You now have high quality MP3 files of whichever recording you converted. These MP3 files will play without a problem on your portable device of choice, and will play in most vehicles' CD players if burned on to a CD-R as part of a data disc.
    • If you need to convert more recordings, start the process again from step 5, but instead click [last used] in the "Converter" context menu.
    • Please do not distribute MP3 files of lossless recordings publicly, but feel free to give copies of the files to your friends who may appreciate the recording.

Converting to WAV format

  1. Drag and drop the files you wish to convert into foobar2000.
    • If the tracks are not already selected, select them all.
  2. Right click anywhere in the selected area.
  3. Mouse over "Convert", then click "..."
    1. Click "Output format".
    2. From the list, select "WAV". Click "Edit".
    3. Click "Back".
  4. Click "Processing".
    • Scroll to the right under the "Available DSPs" box and double click on "Resampler (SoX)".
    • Click on "Configure selected".
    • In the dialog box, click the dropdown box next to "Quality" and select "Best". Click "OK".
    • Click "Back".
  5. Click "Convert".
    1. When asked to pick a directory to place the converted files in, create a directory and double click it, then click OK.
    2. Wait for the files to finish converting. This may take several minutes depending on your computer's speed, and how long the recording being converted is.
  6. You now have uncompressed, lossless WAV files of whichever recording you converted. These WAV files are ready to be burned to an audio CD.
    • If you need to convert more recordings, start the process again from step 5, but instead click [last used] in the "Converter" context menu.
