>From KY8D:
Why be tied to a computer for your CW copying practice? Listen to files on
an MP3 player or your smartphone instead. For your convenience I present
1,000-plus hours of machine-perfect CW exercise files totally free. You
need not even suffer the affront of any advertising. The site is quite
simply my own effort in support of a hobby which I love.
Re-mastered as of today are all of the many CW practice files archived as
sets of MP3s on my website liked-to below. That plus a few new ones added.
Be further aware that as of today I now entertain viewer requests. Some few
restrictions apply, as detailed on the site.
Aside from that, what else has changed? Namely, inside of each file, where
always before a paragraph break was signaled by the BT symbol alone by
itself, now there will also follow three extra spaces affording an audible
pause. Like so in order to emulate that pause in narration as would be made
by an AI or human reader.
The listings have also been re-ordered somewhat. Tone is reduced from 750
Hz down to 700Hz, which is kinder to older ears. Sampling rate has been
reduced to 11,025 kbits from 22,050 kbits (major overkill) thereby
achieving much smaller archives and thus faster downloads.
