AudioGen vs Autunes

AudioGen is a text-to-sound model provided through AudioCraft. It generates audio samples from text descriptions and can continue from an audio prompt, with conditional and unconditional generation modes. Sampling controls include greedy, temperature, top-K, and top-P methods. The listed pretrained model, facebook/audiogen-medium, has 1.5 billion parameters; the example API generates sound and saves it as WAV. The implementation uses an autoregressive Transformer and a 16 kHz EnCodec tokenizer. The repository provides API access and a local Jupyter notebook demo. Running the medium model locally requires a GPU with at least 16 GB of memory; installation requires Python 3.9 and PyTorch 2.1.0, with ffmpeg recommended. The model was trained on English descriptions and performs less well in other languages. It cannot generate realistic vocals, and prompts may need refinement. Code is MIT-licensed, while weights use CC-BY-NC 4.0; training datasets are not provided. The listed self-hosted plan is free.

Autunes is a web-based AI music generation platform that creates full tracks from text descriptions. Its lyrics writer can generate words for a song, or users can supply their own. The site advertises generation across 70+ genres, and says its Zori engine sings natively in 50 languages. Users can download generated music and share it to Spotify, YouTube and social media. Autunes also offers remixing, variations and track extensions; Audio2Audio remix is listed on Pro and Creator. The Free plan is free, billed forever, with 25 lifetime credits, 20 daily credits after exhaustion, and audio up to three minutes. Pro is ₹599 a month, billed as a 30-day pass, with 300 monthly credits, 20 daily credits and three-minute audio. Creator is ₹2,999 a month, also billed as a 30-day pass, with 1,100 monthly credits, 20 daily credits and up to four minutes on the pricing page. Pro allows commercial use; Creator includes full commercial rights, including sync licensing and distribution. Uploaded files and anything made from them remain private to the uploading account. Autunes says generated music is retained indefinitely unless deleted, while usage logs are retained for 90 days.
