I just purchased everyday looper today for my ipod touch 32 gb 4th generation however I am having problems getting it to work. Whenever I record a sound it registers it but instead of replaying the sound it emits a loud buzzing noise. Can anyone help me fix this issue please?

If you just download it, the easiest thing to do is to delete it from your iPod and re-download it. Sometimes apps get corrupt in the download process.
