AVSub News

8th August 2016 - V18 of AVSub is about to enter beta although I've still got one feature left to implement. It will be available some time in September.

4th July 2016 - Chromecast transcoding setup guide has been added to the guides

4th July 2016 - V17 is out now. Internet radio stations, Chromecast video, cache auto-delete, play/shuffle in subfolders (ie artist playback/shuffle), single track repeat, Madsonic video support, new main menu and easier support.

14th June 2016 - AVSub Forum - AVSub now has it's own sub-forum on the Subsonic website. This is a great place to get updates, post questions and request features.

I've just posted a list of did you know? features - see this post.

10th June 2016 - V17 update - I've updated the main menu again (see Twitter)! Also, Internet Radio stations is working nicely, plus I've got Chromecast video working - this will be part of the existing Chromecast in-app purchase (so a free upgrade if you've already purchased it).

6th June 2016 - I've added a reviews page so that I can respond to iTunes reviews. These reviews are a 1-way street and sometimes people will score low without contacting me for help. This is a channel for that.

21st April 2016 - V16 is out now. Full playlist management, 3D touch support and true gapless (finally!)

23rd March 2016 - V15 is out now. This release adds a 10-band equaliser with pre-amp controls, along with a full second server configuration and lots of stability fixes.

20th March 2016 - It looks like one of the previous releases gave away Chromecast support for free! This was never my intention and it was always meant to be an in-app purchase. Sorry if this was misleading - it wasn't a cash-grab!

12th November - V12 is out now! FLAC / ALAC / M4A / Vorbis / Opus support added

AVSub now supports many more audio formats, including both FLAC & ALAC. Checkout the FAQ's for more information.

I also recommend clearing your art cache (new option in Settings) as AVSub now uses a better art sizing algorithm. The app will automatically reload art as needed.

18th October 2015 - I've made contacting me clearer in the header after a comment in an iTunes review - or just send a mail to about@avsubapp.co.uk.

1st Feb 2015 - CarSub is becoming AVSub

CarSub has developed rapidly from it's beginings as a car-based music streamer. The gesture based-interface isn't going anywhere, but the name no longer represents what CarSub is. So, it's getting a new name - AVSub! More news and site updates soon.

17th November 2014 - Cache Guide/FAQs Now Available

The Caching guide has been added to the Guides section, along with a couple of questions answered in the FAQs.
