Introduction
DCR file extension is used by operating systems to recognize files with content of type DCR. Here is some information which will get you started. How to Open DCR file. To see if you have an application which support DCR file format you need to double click on the file. This will either open it with matching application or Windows will suggest.

Files that contain the.dcr file extension are created by certain Kodak digital cameras, usually of the SLR variety. The DCR file format is used to take photographs without the camera making color adjustments or compressing the image file that has been captured by the camera.

The Liberty Recorder creates audio files with a 'dcr' extension. A dcr file is a multi-channel audio / video file with the audio data saved in standard compressed audio file format. The .dcr files could not be given a .wav extension, because other .wav players such as Windows Media Player are not designed to recognize the multi-channel data tracks found within the dcr files.
Both .wav files and .dcr files save the audio data in a compressed PCM (.wav) format. Saving the audio data in a standard, compressed format allows any Windows PC to playback the audio using the Liberty Player.
Compression
The Liberty Recorder can use any standard compression algorithm installed onto the PC. This includes any algorithm provided by the Windows Operating System and any compression algorithm that might be added to the PC. Various compression algorithms have been a standard component of all Windows Operating Systems since Windows'95 and any of these may be used with the Liberty Recorder. These algorithms include, but are not limited to Microsoft ADPCM, and D.S.P. Group Truespeech.
Speex is another compression algorithm that will work with the Liberty Recorder. SPEEX is an Open-Source, patent-free compression algorithm specifically written to record the spoken word, not music. It delivers a high compression rate with very good sound quality. The Speex algorithm may be downloaded using this link. If the Speex codec is used, then please use of one of the Q4 mono (Quality 4) or higher recording attributes. We suggest recording with the Attributes set at '16.8 kBit/s, 16.0 kHz, Mono Q5'. Further information about Speex may be obtained from www.speex.org.
