AVS Audio Converter vs FFmpeg Batch AV Converter

AVS Audio Converter converts audio between popular formats and provides controls for output settings, effects, editing and batch processing. Listed formats include MP3, WMA, WAV, M4A, AMR, OGG, ALAC, FLAC, AC3 and MP2. The full version can trim recordings, remove sections, join files and apply fade-in, fade-out and normalization effects. It can also change track title, author, artist and album-cover information, create M4B audiobooks with chapters and bookmarks, and save edited audio as M4R ringtones for iPhone. Audio extraction is available from DVD, MPEG, MP4, AVI, MOV and WMV files. Batch mode converts or compresses multiple files; the full version adds command-line patterns, presets and scheduled conversions. AVS Audio Converter runs on Windows 11, 10, 8.1, 8, 7, Vista and XP, but not Mac OS or Linux. The free plan adds a voice logo to output, and some features require the full version. Plans list free access, $49 a year, and $79, paid once.

FFmpeg Batch AV Converter is a graphical interface for using FFmpeg's command-line capabilities in audio and video workflows. It supports unlimited single-file or multi-file batch encoding for formats handled by FFmpeg, including MP3, AAC, AC3, FLAC, WAV, Opus, and Vorbis. Encoding options include simultaneous jobs, two-pass processing, fixed output target size, and custom parameters that can be created with an encoding wizard. Users can drag and drop files, track progress, change priority, pause or resume, and set automatic shutdown or folder monitoring. The application also supports stream mapping, multiplexing, demuxing, subtitle processing, trimming, concatenation, thumbnail extraction, image-to-video creation, silence detection, splitting, and chapter creation. It can batch-download YouTube videos, live events, and m3u8 links through a youtube-dl/yt-dlp interface for supported URLs. The free, open-source project has been developed since 2017 under LGPL-2.1. Windows and Linux are supported; Linux use requires Wine 9.0 or higher and wine-mono.
