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.
First released in 1995 and developed by the Fraunhofer Society, the mp3 audio format is arguably one of the most recognizable audio file format that ever existed. This digital audio encoding format hails from the lossy data compression algorithm family. The format enjoys widespread support and compatibility with most handheld music players, smartphones, computers, and in car stereos most of which have native support for the format. It is also a popular format used for distribution of audio files over computer networks such as the internet. Free mp3 encoders such as LAME and audacity give authors the tools necessary to create .mp3 files.
FreeFileConvert uses tuned encoding for AIFF to MP3 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 MP3 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 MP3 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
The MP3 format compression algorithm works through perceptual coding. A technique in which audio artifacts outside the auditory range of the average human, are reduced or 'cancelled out'. The result is a near perfect replication of the original audio sample at a compression ratio of 11 to 1 at 128 kilobits per second. Audio quality can be controlled by such factors as the bit rate, sample rate, among other features. But bits rates being the main determinant of audio quality can be adjusted between the typical range from 128 kb/s to as high as 320kb/s.
Upload your audio file in the AIFF format from your device, Dropbox, or Google Drive.
Select MP3 as the output format and click Convert. Adjust optional settings if needed.
