You might want to listen to the audio from PilotEdge
. Click the 'listen to sample audio' link on the home page, pick a date in the past (ie, not today), then download the 'all day' recording for one of the controlling positions.
There are two advantages to using this for study purposes:
1) all the silences are removed from the recordings, so they move along very quickly
2) the clarity of the recordings is generally very high, making it ideal for ICAO English proficiency
PilotEdge is a network that provides ATC service for a range of flight simulators. What you're hearing in those recordings are the interactions between the pilots and the PilotEdge controllers.
You may want to consider flying on the network to take your training to the next level, but at the very least, I think you might find it helpful to simply make use of our free audio recordings to help with your training.
