Claim 14:
15. A method for decoding an encoding of an audio signal, wherein the method is conducted by an audio signal decoder, wherein the method comprises:
transforming, by a transform unit of the audio signal decoder, a second audio signal portion or a value or signal derived from the second audio signal portion from a second domain to a tracing domain to acquire a second signal portion information, wherein the second domain is different from a first domain, wherein the tracing domain is different from the second domain, and wherein the tracing domain is equal to or different from the first domain, and
receiving, by a noise level tracing unit of the audio signal decoder, first signal portion information being represented in the tracing domain, wherein the first signal portion information depends on a first audio signal portion being represented in the first domain,
receiving, by the noise level tracing unit of the audio signal decoder, the second signal portion information being represented in the tracing domain,
determining, by the noise level tracing unit of the audio signal decoder, noise level information depending on the first signal portion information being represented in the tracing domain and depending on the second signal portion information being represented in the tracing domain, wherein the noise level information is represented in the tracing domain, and
obtaining, by a reconstruction unit of the audio signal decoder, the audio signal depending on the noise level information.
