HiDef Radio 1.0-beta3 (build 11)

Third test build: a fix from a tester's video, a battery saver, and a new piece of logic for frequencies that two stations share.

Two stations on one frequency

In some places the HD on a frequency belongs to one station and the analog you receive to another (seen on 91.1 in the valleys north of Los Angeles: KDSC's HD under XETRA-FM's analog). The app used to swap between the two several times a minute. Now:

• the HD plays alone, and an HD dropout is silence (as on HD2), not the other station;
• an amber line under the signal box says the analog here is another station - tap it to listen to that one instead;
• a saved logo belongs to a station, not to a frequency, so it is no longer shown over another station.

Call letters only when confirmed

An RDS code that spells a US call sign which is not licensed on the tuned frequency is no longer shown as the station's name (XHITZ 90.3 Tijuana read as "WHTZ, Newark, NJ"). Signal details > Station now says what the code spells and where that call is licensed.

Battery: the HD search rests

In Auto, on a station without HD, the HD decoder rests after 30 seconds and takes a 3-second look every 30 seconds. Searching for HD was the most expensive thing the app did. The signal line says "(no HD)" and the details "HD decode resting". HD that appears later is picked up at the next look.

Dongle clock correction is steadier

On stations whose analog and HD audio are processed differently, two or three noisy measurements could produce a wrong figure ("+103 ppm" in a tester's video). The app now checks the audio measurement against the tuning offset and uses it only when the two agree, or when the audio has made a strong case over a longer time.

Also fixed

• Auto > Analog only > Auto on an HD station could put the HD on without lining it up (a 2.5 second jump in the programme).
• A word in the welcome card.

Good to know

• The two-station logic was tested with recordings mixed for the purpose, not yet on the air. If you have such a frequency, a screenshot of the signal details would help a lot.
• Logos saved by earlier builds have no owner yet. They get one the next time that station's HD is received.

Installing

HiDefRadio-1.0-beta3-build11.apk updates the 1.0-beta1 and 1.0-beta2 APKs from this page in place; favorites and settings stay.

It is signed with the developer's own key, so it is a separate install from the Google Play test version: it cannot be installed over the Play version, or the reverse, without uninstalling first (favorites are not carried over). Pick one and stay with it. An APK install does not count toward the Play test - if you can, join the test instead.
