Audio encoder and decoder using a frequency domain processor and a time domain processor

An audio encoder for encoding an audio signal, comprises: a first encoding processor (600) for encoding a first audio signal portion in a frequency domain, wherein the first encoding processor (600) comprises: a time frequency converter (602); an analyzer (604) for analyzing the frequency domain representation up to the maximum frequency to determine first spectral portions to be encoded with a first spectral resolution and second spectral regions to be encoded with a second spectral resolution, the second spectral resolution being lower than the first spectral resolution; a spectral encoder (606) for encoding the first spectral portions with the first spectral resolution and for encoding the second spectral portions with the second spectral resolution; a second encoding processor (610) for encoding a second different audio signal portion in the time domain; a controller (620) ; and an encoded signal former (630). 一种用于对音频信号进行编码的音频编码器，包括：第一编码处理器(600)，用于在频域中对第一音频信号部分进行编码，第一编码处理器(600)包括：时间频率转换器(602)；分析器(604)，用于分
