**Description** I want to add a custom ringtone. I see the delivered PCM binary files are SILK\_V3 encodings (bin\ringtone\ringtone.xml). So in theory I could create a pcm audio file with Audacity or ffmpeg from wav/mp3, then encode the raw audio with the Skype SILK SDK, add the ringtone file to ringtone.xml and localization.xml with a new ID and I should have a new ringtone. I have no luck guessing the ringtone parameters (channels, sampling bits, endianness, frequency, etc.) Can someone knowledgeable please state more details on the format, maybe a code snippet of a function I can use to open say Ukulele.pcm and play with it a bit? Thanks! ---
