Apologies to the list. I sent at least one e-mail (not to the list)
without experiencing the new-line problem, so I thought that it had
sorted itself out.

try adding -twolameopts br=128 -srate 44100 -af lavcresample=44100.
Since it is mono, you can probably use a lower bitrate and sample
rate without affecting how it sounds. 

twolame --help will give you a lot of
information about legal sample rates and legal bitrates for each
supported sample rate.
