Convert to MP3 (Encode, compress)

You can directly convert WAV, OGG, MP3 to MP3

You can
directly convert CD tracks to MP3 with Precision Digital Audio Extractor (All users)

You can
directly convert CD tracks shown as WAV files to MP3 (Windows 95, 98, ME users only)

You can
indirectly convert WMA to MP3 (Convert WMA to WAV then WAV to MP3)

(Re-encoding or trans-coding which is MP3 to MP3 or OGG to MP3 can result in a reduction of quality.
You are re-compressing an already compressed lossy format file. If you have a preference for quality
over convenience, decode the MP3 or OGG to WAV first, then encode the WAV to MP3).


Click the
WAV, OGG to MP3 tab.

Select the
button for the encoding mode that you would like to use: Automatic, CBR-Manual, VBR-Manual, ABR-Manual or Expert.

Make sure an output location has been selected for your converted files by clicking Select Location.

Add
WAV, OGG and MP3 files that you want to convert to the Conversion List.

Click Encode to MP3 when ready. All files in the list will be converted to the MP3 format.



Encoding Modes:


Automatic, Automatic Easy Presets:

Move the horizontal slider to the encoding type that you would like to use,

Constant Bitrate, Variable Bitrate or Average Bitrate (LAME documentation)

Move the vertical slider up and down for the chosen type and see the preset description shown above for an explanation of each preset.

The higher the slider is, the higher the quality will be and the larger the file size will be.

When disk space is an issue, such as for portable MP3 players, move the slider down to lower bitrates to conserve space. Quality will also be lower. Constant Bitrate (CBR) has the best compatibility with MP3 players but potentially larger file sizes when compared with Variable Bitrate (VBR) and Average Bitrate (ABR).

You can also make selections in the check boxes for error protection, copyright, copy and no info. tag settings.



CBR-Manual, Constant Bitrate, manually specify quality settings:

Move sliders and click option buttons and check boxes to specify the bitrate, stereo mode, fine quality adjustment, output sampling frequency, lowpass (hi-cut) and highpass (lo-cut) filtering frequencies, error protection, copyright, copy and no info. tag settings.



VBR-Manual, Variable Bitrate, manually specify quality settings:

Move sliders and click option buttons and check boxes to specify the main quality, minimum and maximum bitrates, stereo mode, fine quality adjustment, output sampling frequency, lowpass (hi-cut) and highpass (lo-cut) filtering frequencies, error protection, copyright, copy, no info. tag and enforce min. settings.



ABR-Manual, Average Bitrate, manually specify quality settings:

Move sliders and click option buttons and check boxes to specify the average bitrate, minimum and maximum bitrates, stereo mode, fine quality adjustment, output sampling frequency, lowpass (hi-cut) and highpass (lo-cut) filtering frequencies, error protection, copyright, copy, no info. tag and enforce min. settings.



Expert, command line mode:

This mode allows you to manually enter commands and values for the most control over the encoding / decoding process. The Easy Entry List helps simplify the entry of commands. Click on any list entry that has a preceding "-" hyphen to automatically enter it in the command line.

You can save your favorite command line entries by using My Presets. See instructions there.
