12 Best Free Audio Amplifier Software For Windows

This is a list of best free audio amplifier software for Windows. Using these software, you can convert low volume audio files into audio files with good volume. Thus, these software come in handy to increase audio to a significantly high level. They not only let you increase the audio level, but also save files with new audio properties.

In many of these amplifier software, you get presets to use for sound amplification. But in most of them, you can perform audio amplification manually too without using presets. These sound amplifier software let you adjust amplification level either in percentage or db. Many of these audio amplifiers even let you have a preview of amplified audio to ensure its quality.

These sound amplifier software support a variety of file formats to import music files and then save amplified audio files. WAV, WMA, OGG, AVI, RAW, MPEG, FLAC, M4A, and AMR are some of them. In addition to audio amplification, these audio amplifier software also let you perform many other operations on audio files having aforementioned formats. They provide options for bass and treble adjustment, change pitch & tempo, noise reduction, normalize, equalize, pitch shift, add noise, audio compression, cassette and voice breath noise reduction, etc.

•  Now, you need to use following command syntax to amplify the audio file:

ffmpeg -i inputfile_name -af "volume=ndB" outputfile_name

In the above syntax, n is any positive integer.

Suppose, you need to amplify an audio file named as Listoffreeware.mp3 with 11dB as the amount of amplification and save it as Outputfile.mp3, then the command will be:

ffmpeg -i Listoffreeware.mp3 -af "volume=11dB" Outputfile.mp3

It supports formats like MP3, AAC, AMR, OGG, FLAC, and many more.

You can also use FFMPEG as a free audio compressor, video resizer, video rotator, video metadata viewer, etc.
