CloudConvert Audio Converter is an online service for converting audio files through a web application or API. It supports AAC, AC3, AIF, AIFC, AIFF, AMR, AU, CAF, DSS, FLAC, M4A, M4B, MP3, OGA, OPUS, SF2, SFARK, VOC, WAV, WEBA, WMA, and other listed types. Conversion controls let users adjust audio quality and file size, and batch conversion is available. CloudConvert serves individual users and corporate customers through its API. Automation integrations include Zapier, Make, Microsoft Power Automate, and n8n; storage workflows can involve Amazon S3, Google Drive, Dropbox, OneDrive, and SharePoint. API v2 includes official PHP, Node.js, Python, Ruby, Java, and.NET SDKs plus a CLI. The free plan costs nothing, with 10 credits per day, a 1 GB file limit, five-minute processing limit, five concurrent tasks, and low processing priority. Package, Subscription, and Enterprise plans list prices as “...” or custom. CloudConvert says files are processed in isolated containers and deleted afterward.

FFmpeg is free, open-source software for recording, converting, and streaming audio and video on Windows, macOS, and Linux. Its command-line tool converts media files between formats, supports local recording, and lists AVI among its output formats. Output protocols include HLS, RTMP, RTMPS, RTP, RTSP, SRT, and UDP. Hardware acceleration is available for encoding and decoding. Decoding support includes Vulkan, VAAPI, and OpenHarmony, and Vulkan codecs can work on implementations of Vulkan 1.3. The Vulkan compute approach supports FFv1 encoding and decoding and ProRes RAW decoding, but only for codecs designed for parallel decoding. FFmpeg’s transcoding components run in parallel, which can improve throughput and CPU use; gains may be limited when one component dominates the processing. The project accepts contributions through its Forgejo instance and offers mailing lists, IRC, forums, bug reports, a wiki, and conferences. Version 8.1 Hoare was announced as available for download on March 16, 2026.
