Mp3/Wav/FLAC/Ogg(包含MP3格式的音频的文件) -Sound Normalizer - 声音等化器确保不受损失ID3标签的降低，改善，恢复Mp3, FLAC, Ogg, APE иWav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2, OGG, A-LAW, u-LAW)文件的质量和规模。
通过对这些文件的试验和音量正常化可以实现上述的改善。
通过内置的编码器和FLAC等化器能够降低文件的规模。
程序有内置的批处理器来Mp3, FLAC, Ogg, APE и Wav(PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2, OGG, A-LAW, u-LAW)文件的批量测试，一批标准化和批量转换。
WAV，FLAC, Ogg, APE和MP3等化使用来正常化音量。
音量大小以图形的形式显示使用百分比值。
WAV，Ogg, FLAC, APE等化器和试验实现根据峰值（高峰等化）或者平均（RMS等化）音量水平。MP3等化和试验实现根据平均（RMS等化）音量水平。
MP3等化和试验实现根据Replay Gain（重放增益）标准。
声音等化器也允许编辑支持ID3v1和ID3v2标签的ID3标签（内置的Mp3, FLAC ID3标记编辑器)；使用Lame 3.99.2编码器为FLAC转换成MP3，FLAC转换成WAV，WAV转换成MP3，MP3转换成WAV，MP3转换成MP3保护ID3标签的文件；使用内置的播放器来听MP3，FLAC和WAV文件。

The Mp3 / Wav / FLAC / Ogg / APE Normalizer - Sound Normalizer reduce, improves, regains a volume and a file size without losing ID3, FLAC, Ogg tags of Mp3, Ogg, FLAC, APE and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2, OGG, A-LAW, u-LAW) files.
Improve of a volume is reached by the test and normalization of the volume level of Mp3, Ogg, FLAC, APE and Wav files.
Reduction of size files is reached with the help of built-in encoders and of the Normalizer.
The Mp3 / Wav / FLAC / Ogg / APE Normalizer allows to fulfill the test and normalization separately for each channel.
The Sound Normalizer contains batch processor and it allows to fulfill the batch test, batch normalization and batch converting Mp3, Ogg, FLAC, APE and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2, OGG, A-LAW, u-LAW) files.
The volume level is represented graphically in percentage or decibels (dB).
The Wav, Ogg, APE and FLAC normalization and test is fulfilled on a peak level (Peak Normalization) and on an average level (RMS normalization).
The Mp3 normalization and test is fulfilled on an average level (RMS normalization). The Mp3 Normalizer allows to modify a volume of a scanned file directly without usage Encoder and APEv2 tags.
The Sound Normalizer also allows editing ID3, FLAC, Ogg Tags, converting FLAC to Mp3 (with saving ID3, FLAC tags), FLAC to Wav, Wav to Mp3, Mp3 to Wav, Mp3 to Mp3 (with saving ID3 tags), Wav to APE, APE to Wav, APE to Ogg, Wav to Ogg, Ogg to Wav files using Lame MP3 Encoder 3.99.2, FLAC Encoder 1.2.1, Monkey’s Audio Encoder 4.11, Ogg Vorbis Encoder 1.3.2 (aoTuV 6.03), listening Mp3, FLAC, Ogg and Wav files using the build-in audio player.
