audio recording quality is terrible, please help

Hi, i have a karaoke app that we ported over for the kindle fire from android and the audio recording is awful. its muffled and very lo-fi. We have tried mp3 as well as 3gp and they both sound the same. It seems like there is some default codec or lo resolution compression happening. Can someone please help?

Hi Listenerkids, Thank you for your post. You have not mentioned how you are encoding input voice data to mp3. LAME, is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL, could be used for Audio Recording. This works pretty fine in kindles I have tested. Sample Implementation of LAME could be found here, https://github.com/yhirano/Mp3VoiceRecorderSampleForAndroid If you still have concern, please post back your implementation sample code how you are encoding the raw audio data.
