The data compression to get a lossless audio, a file format and an algorithm used is APE, also known as Monkey's Audio. This compression can retain data and not suffer losses during its compression as opposed to the other compressions with losses such as MP3, Musepack, ACC, and Vorbis. It encodes and compresses the audio to reduce transfer time, storage space. The audio extension APE is used for an audio file to track the metadata. The format is available freely for users possessing media players and playback plugins.
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 APE to AC3 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload APE 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.
The source code for APE is not considered as an open source. It has a symmetrical algorithm, a process of an encoding comparable decoding which makes the files not suitable for fast players for example Rockbox. To cover this, an independent GPL code is written for and is added in FFmpeg. It also provides limited support to software other than the ones for Windows.
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 APE format from your device, Dropbox, or Google Drive.
