I am developing an app based on soundphrases for android. I record a voice with my samsung galaxy SIII and then use audacity for making the quality better. Then this soundfile is exported as an uncompressed WAVE-file. I compress it to an APE-format with monkeys audio (free opensource) and then convert the ape-format to MP3.
SO my question is - if I want to do something more with these sounfiles - does it matter if I work with the compressed MP3-formats or work with the raw WAVE-file format? Does it deteriorate the quality if I once again open and save the MP3-files? (could be compared with once again opening a jpg pic. in photoshop
