outro and 5s of silence missing at file end

Volume is low (85.5dB) and should be amplified by 3dB. A spike at 18.1s is now preventing amplification. It can be deleted without effect or one can use Effect/Compressor plugin if you are using Audacity. A video describing use of the latter is below. https://www.youtube.com/watch?v=wJ3lOTDsN6c

The original file I downloaded was 22:38. The present one is 22:54 and has the outro but it also has 11s of silence at the end. Only 5s is needed.
