You’d be singing for the eight seconds instead of speaking. That’s only if you want to post a sample to the forum. It will only allow short clips. If you have access to file hosting services, you can post much longer samples. Post only the raw capture, not effects or post processing. Just sing.
Thank you. I’m not at a machine with good monitoring right this second. If you get half-way close, we can usually keep you from making some of the more obvious mistakes. It does worry me that your finished sample is using a lot of echo/reverb on his voice. The Audacity echo generator has never won any awards for high quality and simple use.
