android - getMaxAmplitude() "always" reached -


i want app react on load sound clap. problem is, getmaxamplitude() reaches it's maximum of 32762 when talking in normal voice >= "allmaxampli" variable set in config mode.

the media recorder set this:

mrec = new mediarecorder(); mrec.setaudiosource(mediarecorder.audiosource.mic); mrec.setoutputformat(mediarecorder.outputformat.three_gpp); mrec.setaudioencoder(mediarecorder.audioencoder.amr_nb); [..] mrec.setoutputfile(audiofile.getabsolutepath()); mrec.prepare(); mrec.start();

and check done (abstracted):

int maxamp = mrec.getmaxamplitude(); if (maxamp >= calibamp)   log.v("id", "max amp greater!");

did miss something?

is there other way measure volume, or increasing limit getmaxamplitude? thought using audiorecord, i'd have calculate amplitude hand. wanted save myself that.

i searched quite bit before considering posting, unable find anything. appreciated.

/edit: if calculate decibel out of amplitude, other values? might solve problem then.

/edit2: calculated decibel out of amplitude, problem persists, since amplitude high time. nobody has idea? :/

/edit3: after testing other apps seems general problem android. why every sound measuring app free..
