Those of us who do voice overs from a home studio (and it's increasing every second) depend heavily on the Internet. Pre-Internet, voice talents would go out to recording studios to do the work. And while being able to record and then send our work to our customers/clients online is a blessing (no rushing in traffic to get to a voice over session), you still have to make sure that the voice work you record makes it to its destination-the producer, director, or individual who hired you. There are many audio delivery services on the Internet that can help you do that. The one I use is Send This File.com which I find to be dependable. And some of them are free... up to a certain point. But putting ONE simple sentence in your emails to your customer or client after you email a link for them to download your voice over works like magic. And here it is. "Please confirm receipt of the voice over." Never assume that your work has gotten to its intended destination. Sometimes, even though you put the confirmation request sentence in your email, some clients will not email back and say something like, "Thanks 'Randy'... audio/voice over received." Make sure that once you send out your work, you follow up promptly. Some voice over talents will have a download option right on their websites, so the customer/client can log in with a password and download their audio. That's a really cool and efficient option for both parties. And as many know, sometimes emails and such default to spam folders. If you're doing business over the Internet, you should be checking your spam folder throughout the day. I like to tell a first-time customer how I will be delivering the voice over to them before I start the job. Some large companies have strict email settings that won't allow incoming emails such as download links. Let your customer/client know the process up front so you won't be having any problems later. It's a simple thing, but it's all about making your recording and delivery service smooth and professional with no entanglements.
Of course, all of the above information applies to those who are not doing a directed session where the producer/director is using ISDN or Source Connect, in real time, to capture the voice over recording on their end.
And some e Learning companies I work with have me upload the audio files to them using FTP-"file transfer protocol" where I log in using FTP software and do an audio upload. Very convenient.
