Abstract:
For supporting a selection of a predictive or non-predictive quantization in the scope of an audio signal coding, it is determined whether an error resulting with a non-predictive quantization of an audio signal segment lies below a predetermined threshold value. An audio signal segment quantized with the non-predictive quantization is provided as a part of an encoded audio signal at least in case it is determined that the error resulting with the non-predictive quantization of the audio signal segment lies below a predetermined threshold value. Otherwise, an audio signal segment quantized with predictive quantization is provided as a part of an encoded audio signal.
