HiDef Radio 1.0-beta2 (build 7)

Second test build, with fixes from the first test reports.

• Dongles without a TCXO (many older RTL-SDR dongles, such as a 2014 Nooelec R820T): the blend from analog to HD never started. Their crystals can be 50 ppm off and more, so the analog audio crept away from the HD audio. The app now measures the dongle's clock against the station's and corrects the analog audio. Tested with recordings turned into "cheap crystal" recordings; confirmation from a real dongle is welcome. Details: How the blend works.
• After a USB hiccup (lost samples) the analog and the HD are lined up again within seconds.
• "MHz" no longer breaks in two on narrow phones.
• New: a short welcome card on first start, also under Settings > About > Getting started.
• The signal details show the dongle's clock error ("dongle clock +57 ppm"). If you test, please tell me your number, phone and dongle.

Installing: download HiDefRadio-1.0-beta2-build7.apk below and open it on the phone. It updates the 1.0-beta1 APK from this page in place. It is signed with the developer's own key, so it can't be installed over the Google Play test version, or the other way round: uninstall first, and favorites are not carried over. APK installs don't count toward the Play test. To help with that, see Get the app.
