Smart Automatic Cover Art Downloader SACAD is a multi platform command line tool to download album covers without manual intervention, ideal for integration in scripts, audio players, etc.

? Features ? Can target specific image size, and find results for high resolution covers ? Support JPEG and PNG formats ? Currently support the following cover sources: ? Last.fm ? Google Images ? Amazon CD (.com, .ca, .cn, .fr, .de, .co.jp and .co.uk variants) ? Amazon digital music ? Smart sorting algorithm to select THE best cover for a given query, using several factors: source reliability, image format, image size, image similarity with reference cover, etc. ? Automatically crunch images with optipng or jpegoptim (can save 30% of filesize without any loss of quality, great for portable players) ? Cache search results locally for faster future search ? Do everything to avoid getting blocked by the sources: hide user-agent and automatically take care of rate limiting ? Automatically convert/resize image if needed ? Multiplatform (Windows/Mac/Linux)

SACAD is designed to be robust and be executed in batch of thousands of queries: ? HTML parsing is done without regex but with the LXML library, which is faster, and more robust to page changes ? When the size of an image reported by a source is not reliable (ie. Google Images), automatically download the first KB of the file to get its real size from the file header ? Process several queries simultaneously (using asyncio), to speed up processing ? Automatically reuse TCP connections (HTTP Keep-Alive), for better performance ? Automatically retry failed HTTP requests ? Music library scan supports all common audio formats (MP3, AAC, Vorbis, FLAC..) ? Cover sources page or API changes are quickly detected, thanks to high test coverage, and SACAD is quickly updated accordingly
