128k, 192k, 256k – what?

Hey, there!

Digital audio files are described, as most things digital, with a lot of numbers.

And the numbers you see in the description of an MP3 file can be confusing.

So what does 128k (or 128 kBPS) actually mean?

In digital multimedia, MP3 files included, the bitrate represents the amount of information, or data, that is stored per second/minute/whatever of a recording.

That final “s” in kbps stands for “seconds” – so there are 128,000 bits of data in every second of a 128 kbps MP3 file.

And like a lot of math, more is better. 128 is better than 96, 96 is better than 64.

Better sounding that is, because more data per second means better definition of the sound, but with every higher number, the size of the file increases greatly.

Napster ruined a whole generation’s idea of what good sound is by defaulting to 128 kbps sound files. And stereo ones, no less, so it’s really 64 kbps per channel.

One more reason to go back and look at Napster with disgust.

But – setting your MP3 encoder at 128 for your auditions is just fine. They’re mono.

Hope this helps.

    I feel really good about my demo. It is a quick and fun process, even for someone like me who gets very self concious. :)

    The demos are great. Superb quality. Why go anywhere else?

    Having a well-produced demo is one of the most important things in the VO business. I had a number of demos made from other producers in the past and they all had one thing in common — that manufactured, cookie cutter sound!
    What sets David apart from the rest, besides his affordable price and tremendously fast turn around time, is that all of the clips you record with him sound unique. Each spot sounds like an actual commercial you recorded for a job.
    My agent loved the quality and even asked who produced it to refer his other talent there!

    Thanks again, David for producing such a great, high quality demo for me. You made the process relaxing and enjoyable. I urge anyone reading this unsolicited reply to listen to David’s student demos to hear the difference for yourself. Anyone would be lucky to work with him

    I can not thank you enough. I worked so hard on 15 page IVR project, one day I cryed, look for answers, pull my hear (not really) but I was about until another VO send me this great tool. Thanks!

    When v123 indicates the audition is for a student/ nonprofit are we to assume it is for $0. If so, why does the audition ask for an amount to be entered?

    David,
    I did get this scam through Voice 123. In our discourse, they offered me the gig and they gave me the name of a legit local place to record and the same runaround with the money. I didn’t send anything, but instead, I called the studio to make sure the booking was for the day we set up, and lo and behold, the people there had no idea what I was talking about. I then tried to call back my “contact person” who was setting this up and there was a fax machine beep on the other end. I immediately contacted Voice 123 and told them what had happened. You know what they say…if it sounds togaed to be true, it probably is. Thanks for the reminder!
