The Waveform Audio file format associated with the .wav filename extension was a format developed through collaboration between Microsoft and IBM. It is an extension of the RIFF and was first released in 1991. It is one of the earliest standards used for encoding audio bit streams on personal computers. It is typically used for storing uncompressed raw audio files on the Microsoft Windows platform, however it enjoys cross platform support on Macintosh and Linux and does have support for compressed audio. Because of the relatively large file sizes of uncompressed .wav files, the WAVE format in unpopular for file distribution over limited bandwidth computer networks including the internet.
Files with the .ac3 filename extension refer to the proprietary audio file format Dolby digital AC-3, developed by Dolby Laboratories. The AC-3 format is from the lossy family of audio compression formats. It supports a variety of audio channel configurations and was the first of its kind to support the full surround sound experience. Because of this, the format has been commonly used in the development of motion picture features designed for theaters and in consumer homes through DVDs and surround sound home theater systems. The AC-3 format is one of the supported audio codecs of the ATSC standard ' a set of standards developed for digital television transmission in several affiliated countries.
FreeFileConvert uses tuned encoding for WAV to AC3 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload WAV files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized AC3 results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent AC3 audio with dependable progress tracking.
Bit stream encoding in the WAVE file format is achieved using the linear pulse code modulation format. It has three main data blocks and one to many number of wave chunks identified as the chunk ID, chunk size, wave ID, and finally the format information and the sampled data. Data storage is based on the little endian byte order.
The AC-3 audio encoding format supports between one and six channels with frequency ranges from 20 hertz to 20 kilohertz. The format contains frame headers which detail information about the rate of sampling, encoded channels, bit-rate among other details. It also consists of six audio blocks.
Upload your audio file in the WAV format from your device, Dropbox, or Google Drive.
