The header specifies which data chunk(s) are in the file (normally there's just a single chunk consisting of all the audio), info about what format it’s in, and possibly some other rudimentary metadata. This parameter determines whether to include a WAV header in the file.Īlthough it has become a de facto standard that WAV files contain 16 bit, 44.1 kHz stereo PCM audio data (as on audio CDs), what actually makes an audio file a WAV file is not the format of the audio data itself but the presence of a WAV header at its beginning. When this option is enabled, EAC will add these tags to the compressed files (only if the file format supports ID3 tags).ĭo not write WAV header to file (Default: disabled) If you were to choose Microsoft PCM Converter as the codec, and 44,100 Hz, 16 Bit, Stereo as the output format, it would be the same as doing an uncompressed CD rip.Īdd ID3 tag (Default: disabled, Recommended: enabled) some codecs only support 4 bit resolution). Which options are available here depends on the codec selected at the Wave format option (e.g. With this option, different combinations of parameters for the compression and output format can be chosen, such as sample rate, resolution, mono/stereo.
The codec to choose depends on what should be achieved with the compression (sample format, compression ratio, etc.). When new codecs are installed, they should show up in this list. In this drop down box, all codecs installed on your system are listed. An external compressor is a separate program that can be run directly from a command shell with various arguments telling it which file to compress, what tags to add, the output filename, etc.
Today, most people ripping music CDs don't use internal codecs they use an external compressor, which is configured in the External Compression tab. When using an external compressor, you of course cannot use an internal codec. EAC.Īll options are greyed out here if Use external program for compression in the External Compression tab is ticked. These aren’t programs you run directly they’re just converters invoked from within another program, e.g.

Windows comes with a few such codecs installed already. containing audio in the ADPCM format or as a rare way of storing MP3 data), although the options do allow for writing other formats.Īn internal codec is a CBR (constant bit rate) audio converter library managed through the Windows Audio Compression Manager (ACM) legacy interface, and it typically has a filename ending in. Generally speaking, EAC’s internal codec support is for writing unusual WAV files (e.g. After audio data is read from the CD, EAC will pass it to the codec, and will write the codec's output to a file. This tab allows you to select and choose the options for an internal codec. It is important that the user has a general understanding of what these settings do and how they possibly change the behavior of EAC and/or the codec/external compressor.Įxample settings compression options, Waveform tab
So, often no clear recommendation can be given. Note: many options are dependent on the codec or external compressor (encoder). Here the user specifies how EAC is to behave when they press the MP3 Button in the main window or select compressed items under the Action menu. In Exact Audio Copy’s compression options dialog (keyboard shortcut: F11) are found all options regarding the creating of compressed audio files.
