audio.cpp 0.7: 62 audio model families, Arena UI for local model comparison

audio.cpp version 0.7 has been released, expanding the project to 62 audio model families with over 85 model variants available for local inference. New in this release is an Arena UI that lets users compare models side by side locally without sending audio to cloud services, and support for recent MiniMax audio models. audio.cpp follows a similar architecture to llama.cpp but focuses entirely on audio generation, voice, and speech models.
