IMPROVEMENT OF SOUND

You will find enjoyment in the upper class of converted sound thanks to the built-in volume adjuster and audio effects.

EXTRACT MULTIPLE AUDIO TRACKS FROM VIDEO

To MP3 Converter separates and transforms to MP3 format ALL audio streams from a video (including VOB video files, in native version). MP4, WMV, AVI, or MKV video files might contain a few audio tracks. These tracks can carry the audio of different languages or different audio formats or audio codecs. The majority of MP3 encoders capture only a single audio track defined as primary by the movies’ creators. Even so, if you would like to extract all audio tracks from a video, you have to use a special application. This app is an ideal tool for such an occasion – it rips every audio stream from a video. Thus, you only have to choose – which audio stream you prefer since this mac app will process all audio streams.
 

CONVERSION IN 2 CLICKS

To convert media files to .mp3 format, simply select a destination folder and drop your files or folders to the app’s icon or interface. Converter advises when processing is made and if there are any failures. Conversion is done with full utilization of existing CPU cores, and also it is “crash-free” due to the use of external processes.
 

SETTINGS CONTROL

By default, the converter applies automatic settings for output MP3 files. Automatic bit rate, sample frequency, and channels ensure the best possible MP3 sound quality and save hard drive space by avoiding useless upsampling.
You can also adjust MP3 output characteristics in the Preferences:
- Variable or Constant Bit Rates.
- Preferred constant bit rate from the range: 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 or 320 kbit/s.
- Variable bit rate range can be settled between 8 and 320 kbit/s.
- Channel mode between Mono, Stereo, Dual or Joint.
- Cyclic Redundancy Checks option, which improves error protection.
