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.
The AMV video file format is a proprietary video container which was created for Chinese made and video enabled S1 MP3 players and MP4 players. The goal of the format was to primarily lower the cost of hardware components and royalty fees required for video playback using other container formats on these video enabled devices. The .amv file type is a modified version of the more commonly known AVI multimedia container with the video codec being a version of motion JPEG (MJPEG) format.
FreeFileConvert uses tuned encoding for AIFF to AMV conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload AIFF files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized AMV 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 AMV audio with dependable progress tracking.
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
An open source AMV encoder and decoder for windows exists but is not associated with the original developers of the format. The audio stream within AMV files is encoded using a variant of the Adaptive differential pulse-code modulation or ADPCM algorithm developed by the interactive multimedia association (IMA) but not in its strict form given the inclusion of an 8 byte seed at the start of every frame.
Upload your audio file in the AIFF format from your device, Dropbox, or Google Drive.
Select AMV as the output format and click Convert. Adjust optional settings if needed.
Download the converted video file. Each file stays available for up to 5 downloads.
