Inspired by iSounds, Echo will Make your device come alive with custom sounds such as App launched sound, lock sound, unlock sound, start-up sound, and several more. Included are some free license sounds. You can import your own sounds by copying them to /var/mobile/Library/Echo.
All sounds use the ringer volume. If the custom volume is enabled, the ringer volume will be changed to custom volume while the sound is playing and reverted back to the original volume after the sound is played.
There is no need to respring for the changes to take effect. To disable custom sound choose None. To import your own sounds copy them to /var/mobile/Library/Echo. Audio cannot be longer than 30 seconds and should be in .caf, . aif or .wav format.
