Audio recording and tick/scratch reduction for e.g. vinyl records

This is version 1.6P-7 of GramoFile patches are from the debian package. With this program you can record audio of for example gramophone records, process the signal and listen to the results. Because sound files of the .WAV-format are used, it is possible to exchange the files with many other programs. Cdrecord1 can burn CD-Recordables of these, so you can make CDs with the music of your favorite records. The user interface of GramoFile has a windows-like look-and-feel, making it fairly easy to use.

One of the most important parts of GramoFile is the ability to process digital audio signals. Through the application of several filters it is possible to accomplish a significant reduction of disturbances like ticks and scratches.

Another interesting feature is the track splitting. Just make one .wav file of an entire side of an record and GramoFile will detect where the individual tracks are located. This happens fully automatically, without need to set any options. More experienced users may fine-tune the algorithm, or change the detected track starts and ends, but generally that will not be necessary. Track-times are saved in an editable plaintext .tracks file, that will be used during the signal processing to produce one processed .wav file for each individual track.
