The AVI file format is one of the most widely used multimedia containers ever devised. AVI, which stands for audio video interleaved, was first introduced to the public by Microsoft in 1992 as part of their 'video for windows' multimedia framework. Being a container format, an AVI file with the .avi filename extension can exist with both video and audio content synchronized for playback. The format can thus be used by authors to edit and encode audio video sequences or just video sequences. The Digital video AVI format exists in two forms, Type 1 and Type 2.
The audio interchange file format, and its associated .aif filename extension, is one of the earliest uncompressed audio file formats released for personal computers. The format had its initial release in 1988 and was developed by Apple Inc. using the IFF ' interchange file format, developed by Electronic Arts, as a template. Because the format is inherently lossless, files tend to be large when pitted against lossy audio file formats. Because of this, .aif files are best suited for local storage and playback.
FreeFileConvert uses tuned encoding for AVI to AIFF conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload AVI files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized AIFF 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 AIFF audio with dependable progress tracking.
The AVI format was derived from the RIFF or resource interchange file format which is a generic container format. Digital video that is interleaved can be stored natively as a single stream conforming to the type-1 specification of the AVI file format. This has the disadvantage however of not being compatible with the video for windows framework. In general, the number of blocks in .avi files determine the amount of overhead. Overhead associated with the audio stream is determined by which codec is used to encode the stream for example AC3 or MP3-VBR.
The AIFF format uses the pulse code modulation technique to sample analog audio. A one minute sample at 44khz is comparatively larger than a standard mp3 file of the same sample by approximately 10:1. The format supports metadata including copyright information, comments, authoring information, as well as the ID3V2 tag
