One item which has (i believe) been touched upon, but may not have been
explained deeply enough is the SIZE of the resulting audio file if you
use the default record settings often offered by many (most) audio
recording softwares.
I've found that it's not necessary to use the highest fidelity recording
parameters when recording SSB voice or CW... and possibly digital as well.
Quite often your recording software will default to record parameters like
Record Sample Rate: 44,100 samples/sec
Sample Format: 32-bit float
Recording Channels: Stereo
Export Format: WAV (Microsoft 16 bit PCM)
Using these defaults will result in a very large (many MB per minute
of
record time) WAV file, even if you only record for 1 minute... .
IF given the opportunity to change these defaults, I'll try to select:
Record Sample Rate: 11,025 samples/sec
Sample Format: 16-bit (even 8-bit if available)
Recording Channels: Mono
Export Format: WAV (Microsoft 8 bit PCM)
These settings will result in a very usable quality recording and at about
10% the file size of the default... usually 4 MB for a 5-minute recording.
Just a thought!
