Consolidating itunes libraries
A hybrid example is attempting to record live, but stopping and starting at each flub or mistake, and going back and editing to clean things up, or connect the various live takes.
Mega Seg is a very useful tool in all these cases, as it gives you the ability to have all your media cued up and ready to go for a live record, including on-the-fly insert of sound effects, station IDs, or starting segments like music breaks, sponsor breaks, pre-recorded interviews, etc.
However, to maintain full functionality you will need to stay on Sierra 10.12 or El Capitan 10.11 with i Tunes 12.7.1 or older, as an issue in High Sierra and i Tunes 12.7.2 has hampered full support of protected DRM music (m4p files).
We've reported this issue to Apple, and they will hopefully resolve the problem in a future system update.
(Take care to prevent a feedback loop by either using a second USB audio device, or muting the encoder’s monitor output if possible.) For specific audio routing and recording tools, see the answer under Audio Output / Recording.
Fewer tech issues and longer use — That’s money saved.
Also consider today’s Macs can boot Windows if needed.
Note the Nicecast encoder captures Mega Seg’s audio directly, while other encoders use an audio routing tool called Soundflower (free) or Loopback to direct Mega Seg’s audio to the encoder.
With Soundflower, open Mega Seg’s Settings Devices tab and change Playlist Output to “Soundflower (2ch)”, and do the same for the encoder’s audio input.
