AudioCast S 4+

I agree with the last reviewer. I did find it was good linking my Vast dlna devices and it synced them very well as one device but a recent update 6 months ago stopped the app finding my devices. I know it was not designed for my devices but the user side of the app was great for what i needed it for. The update was quickly reversed within 2 or 3 weeks and it now works as it did before but it now says another update is available and I'm reluctant to download it. So it is a good app but it might have changed if the update is anything like the last one.

I have two AudioCast M5 devices and was looking forward to using them as a cheap multi-room Sonos alternative.

The app does indeed allow you to sync the two devices so that the same audio plays through the two speakers at roughly the same time.

I have used the WHAALE app for this in the past, and the two speakers can have a time delay of ~350ms. In WHAALE, you can adjust the delay manually, which while accurate, is also a chore.

In this app, is automatic, but not quite perfect.

I would guess that it's still out by about 20ms just by ear.

It would be nice if the app gave you the ability to auto correct the delay, and then give you the option to manually tweak it +/- 10%.

Otherwise a superb app.

I bought two AudioCast devices a few months ago. They were never brilliantly reliable but they worked ok most of the time and it was nice to be able to play the same music in two different rooms. Since updating my OS to iOS 13, I can no longer pair with the devices. I’ve tried rebooting phone, unplugging the devices, reinstalling the app, all to no avail. I followed the link to app support, and was taken to a website that doesn’t mention AudioCast, and has a link to ‘support’ that is broken. As things stand, I’ve spent £60-odd on two devices that are effectively useless after a few months.
