Configurations disclosed herein include systems, methods, and apparatus that may be applied in a voice communications and/or storage application to remove, enhance, and/or replace the existing context. Particularly, certain embodiments contemplate suppressing the context component from the digital audio signal to obtain a context-suppressed signal; generating an audio context signal that is based on a first filter and a first plurality of sequences, each of the first plurality of sequences having a different time resolution and mixing a first signal that is based on the generated audio context signal with a second signal that is based on the context-suppressed signal to obtain a context-enhanced signal, wherein generating an audio context signal includes applying the first filter to each of the first plurality of sequences.
