The exact numbers depend on the bitrate, sample rate and number of channels, but as an example, a 100KB, 128kbit mp3 has a playback time of over 7 seconds, and if it's 44KHz stereo it will be about 1.3 megabyte when decoded. SoundPool is meant for short, sound effect style sounds that require very low latency and low CPU overhead. For longer sounds, you should use MediaPlayer. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
