If you set this value to minus infinity, all sound data will be used. You should set this parameter a few dB above what you consider to be silence. This is useful to eliminate any silent sections from the RMS calculation. Any sound material below the threshold will be ignored in the calculation. Normalizing a peak to 0 dB is OK, but normalizing RMS to anything above -6 dB can compromise sound quality.ĭrag the fader to determine the level of material you want to include in the RMS calculation. If you were to do so, all of the dynamic range of the signal would be squashed and all the peaks would either be clipped or seriously compressed. Normalizing to 0 dB boosts the signal so that it has the same apparent loudness as a 0 dB square wave (which is incredibly loud). When using RMS levels, set the Normalize to fader to -6 dB or less. This allows you to preview different Normalize to level settings without rescanning the entire file.ĭrag the Normalize to fader to specify the new average RMS level for the selection. Clicking the Scan Levels button stores the current Peak and RMS values. When previewing, the entire file must be scanned - even when previewing a small selection. This is helpful for matching the apparent loudness of different recordings.Ĭlick the Average RMS level radio button. If you have an eye for detail and can’t stand it when something is almost right but it stumbles at the threshold, you might like an application such as Audio Normalizer.When you normalize using average RMS level, the average RMS value of the sound file is raised to a value you specify. The program helps you apply some changes to your audio files so that they sound better. To be more specific, what it does is carry out loudness normalization, and in order to complete this task, it requires little to no help at all on your side. Helps you analyze and normalize loudness in audio filesįirst off, let’s take a look at the program’s user interface. A dark main window comprises the entirety of the program’s features, making it an intuitive tool for all users out there.Īs such, you need to start by selecting the files you want to process. In case you are wondering about the supported formats, it is worth pointing out that the range is quite wide and includes options such as MP3, AAC, FLAC, OGG, WAV, WMA, and other popular alternatives. Comes with support for the most popular file formats Once you have decided on the tracks you want to normalize, you are prompted with all sorts of details on each and every item. Its size, processing status, codec, duration, BRM, bitrate, and other specifics are gathered in a table.Īs regards the output settings, there are a series of choices here too. You can opt to convert your audio file, select one of the available modes, tweak the target loudness, as well as modify the sample rate, bitrate, and more. All that is left for you to do is indicate an output location and allow the application to normalize the loudness level.Īs you can see, Audio Normalizer is a pretty straightforward application that offers a simple means of analyzing and normalizing the loudness in your audio files. The program processes files quickly, and its performance during our tests on a 64-bit Windows 10 PC proved flawless, so you should take it into consideration if you want your tracks and recordings to be just perfect.The Sound Normalizer increases, reduce, improves, regains a volume and file size without losing ID3, Mp4, FLAC, Ogg tags of Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2, OGG, A-LAW, u-LAW) files. It is reached by the test and normalization of the volume level of Mp3, Mp4, Wav, FLAC, Ogg, APE, AAC, ALAC files. It contains batch processor, which allows to fulfill the batch test, batch normalization and batch converting of Mp3, Mp4, Wav, FLAC, Ogg, APE, AAC, ALAC files. The Mp4, Wav, Ogg, APE, AAC, ALAC 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 Tags.
