Claim:
1. A system for repair of compressed audio signals, comprising: a processor; a sampler module executable by the processor to provide sequential samples from an audio signal; and a signal enhancer module executable by the processor to receive one or more sample components of the audio signal to identify lost parts of the audio signal in the one or more sample components of respective sequential samples; wherein the signal enhancer module is further executable by the processor to provide a corresponding signal treatment and to apply the corresponding signal treatment to each of the one or more sample components of respective sequential samples having a corresponding identified lost part, wherein the processor is configured to determine a quality of the audio signal and to adjust a gain for each corresponding signal treatment that is applied to the respective sequential samples having the corresponding identified lost part based on the determined quality, and wherein the corresponding signal treatment includes one of a bandwidth extension, an in-band harmonic fill, a transient enhancement, a sound stage expansion, a reverb fill, a masked signal fill, and a harmonic phase alignment.
