Claim 0:
1. An audio signal decoder for decoding an encoding of an audio signal, comprising:
a transform unit for transforming 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
a noise level tracing unit, wherein the noise level tracing unit is configured to receive a 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, wherein the noise level tracing unit is configured to receive the second signal portion being represented in the tracing domain, and wherein the noise level tracing unit is configured to determine 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,
a reconstruction unit for obtaining the audio signal depending on the noise level information.
