Can I splice sevral track together with either of the above programmes?
No that is not possible with this software.
There are no editing features built into it. It can only download and convert (immediately post-download conversion only) media files.
Many thanks for your prompt reply.
Is there any software you can suggest for joining audio tracks together?
I don't personally have any recommendations.
The only one that I would be able to think of is probably something like Adobe Audition, but that might be a bit excessive depending on your needs.
I definitely don't have any suggestions for basic but effective programs that offer good value for money.
Sorry I can't be more help.
