14 DAY TRIAL // Windows Phone 8 GDR2 (General Distribution Release 2), the updated flavor of Microsoft’s mobile operating system that started landing on compatible devices recently, will bring along expanded support for .wav files, recent reports on the matter suggest.
According to allaboutwindowsphone.com, the new OS flavor is capable of playing compressed .wav files, courtesy of support for Ulaw and GSM6.10 codecs, both of which enable audio to be squeezed into smaller files, most popular in voicemail systems.
Apparently, Windows Mobile and Windows Phone 7 did land with support for these codecs, but Windows Phone 8 didn’t and many users found their voice mail systems to be unsupported, something that changes in GDR2.
In the table above, AAWP compared codecs support on Nokia Lumia 720, which is powered by WP8 GDR1, and Nokia Lumia 925, which runs under GDR2.
