Abstract:
1. A method for processing an audio signal, comprising: receiving a plurality of frame data including first frame data and second frame data encoded by at least one coding scheme; obtaining first flag information indicating whether the first frame data and the second frame data are encoded by a frequency domain transform coding scheme, respectively; decoding the first frame data by the frequency domain transform coding scheme based on the first flag information when the first frame data is encoded by the frequency domain transform coding scheme; obtaining second flag information indicating whether at least two subframe data are encoded by a time domain transform coding scheme or a time-frequency domain coding scheme when the second frame data is not encoded by the frequency domain transform coding scheme, the at least two subframe data being included in the second frame data; decoding the subframe data by the time domain transform coding scheme or a time-frequency domain transform coding scheme based on the second flag information; and compensating for discontinuity existing between the first frame data decoded by the frequency domain transform coding scheme and the subframe data decoded by the time domain transform coding scheme, wherein the time-frequency domain coding scheme is a time domain coding scheme including a frequency domain transform.
