3 songs about be played on FM radio - but timing is off

[[Member smul…]]

Feedback I received from an audio engineer in an FM radio station ready to play my songs is that my voice though good is off tempo in these tracks.  How can I correct the timing? Is there any software or service available? I have an old Macbook, Ubuntu 18.04 LTS and a Windows Surfacebook.

You need to correct the timing BEFORE you upload the song. On Android there should be a slider for that on the review screen. On iOS it is not necessary. 

You cannot change the timing once the song was uploaded.
