Hello everyone,

I have a client who needs a message on hold done and it needs to be saved as 8bit/8kHz.  I understand that this is quite common, but I have not run into it yet.

I work on a Mac (using Logic) and I am not able to find this setting.  I can find the 8bit but not the 8kHz.  In doing some research it looks like I need to download some sort of audio converter to make this happen.  Does anyone have experience with this?  Can you recommend a good program/converter to download?

Thanks in advance for all of your help.

Have a great day,Judy

Hi, Judy.  If you are going to do telephony this is the most widely used format for US applications.  Unfortunately I'm not a mac person so I can't show you how to make the conversion but I know someone who can help.  Liz deNesnera.

She can do the conversion for you if you like or else I'm sure she'd show you how to do it with the software you're already using.   Liz is very knowledgeable.

Good luck with it.


Hi Judy.  I'm using the excellent but low-cost Twisted Wave on Mac and it will record and/or convert for 8/8.  Doesn't sound at all bad, apart from the sharp audio cutoff at 4kHz - but that's adequate for phone lines.  TW (Mac only) offers free trial.

Judy - 

I also use Logic and was surprised to see it didn't have an export function that went that low when a major gaming software company approached me for an IVR job last year.

The gig required that I send them the output in their phone system's archaic audio format, and if I recall correctly, I used an audio conversion program called Switch to do the job. It has tons of different formats and bit/sample rates, including several for telephony, and can process whole batches of files at a time. The documentation and support may be sparse, but it's pretty simple to use, and best of all, it's free!

Good luck!

Roxanne, Howard and Scott,

Thanks so much all of you!  All great ideas. I have several now to choose from and work through, so I'm sure I'll find something to make it work. 

Scott -- I am finding that there not too many of us who use Logic (I am using version 8).  It's working for me just fine.  However, I do have an editing question.  When taking out a breath our long pause I find that the two regions on either side of the break stay apart.  Is there a way to make the regions "click" together automatically once you take out a pause?  That would make editing so much more efficient. 

Thanks again everyone,


Hi Judy -

Good luck with whatever you direction you go!

Even if you don't use it for this project, I still suggest you grab a copy of Switch and check it out, as I've used it for other features as well - for the price, it's nice to have as an extra tool in the box. 

Yes, Logic users in VO are indeed rare, probably because years ago before Apple acquired the rights to the program from Emagic, the original German developers, it was known to have a lot of features, but also a very steep learning curve. Digidesign (now Avid) took advantage of this, and managed to make ProTools a bit more user- and platform-friendly, and capitalized on it. The result is what you see today, a massive penetration of the product in the market so huge it's the de facto recording tool for most studios (ironically, I was one of the first users of Digidesign's predecessor to ProTools called Session8 back in the early-mid 90s!). 

Regarding your question about auto-snapping or stitching the regions together, unfortunately, I don't think there's a feature like this in Logic, although I've seen it in other programs...I've always pretty much done such editing/tweaking manually because the results sound more natural, and even the guys I see in the studios here in NYC juggle and shuffle regions around manually in ProTools for the same reason.

The closest I've come to this is using the Strip Silence feature to create the regions and then drag them, but I don't even use it that much anymore because it usually ends up clipping the beginning or ends off my words, and it's just faster to use a good noise reduction app and well-placed cut points.

There's a lot of hidden functionality in Logic, though, so I wouldn't be surprised if it's an existing, not-well-documented feature. That said, I also wouldn't be surprised if it's not in there either. Remember, Logic was (and still is) primarily a music-focused recording/composition app vs. a VO-oriented one, but many think it's got more bang for the buck than ProTools (which is why I chose it). All apps have their pluses and minuses, and unfortunately this is one for Logic..Adobe Audition has a lot of features that are great for VO, but I totally hate their new interface, which was FAR more usable back when it was Cool Edit...remember, ProTools didn't even have an internal MP3 export feature until just a couple of years ago!


I did end up going the "Switch" and it worked great.  It only took me a bit to figure out and most of all the client was happy.  So thanks so much.

Interesting stuff on Logic and ProTools.  Even though ProTools is the industry standard I have been told that it can be "overkill" for VO use.  However, I wanted a program I could "grow" into, so upgraded to Logic when I bought my Mac (which I love).  I have the 30-day free trial of Twisted Wave.  I've heard lots of good things about it and it seems to be widely used and liked by many of the pros.  Even though you can only do one track on Twisted Wave, it would perhaps still be a good way for me to record and edit the audio (with the automatic snapping together of regions) and then I could import the audio into Logic if I needed to add another track such as music.  

Interesting to hear about CS5.5 (I believe it's CS6.0 now) for Audition.  I have been considering trying this as well.  So we'll see.

If you happen to live on the east coast, I hope this message finds you dry and safe.

Thanks again for your help,
