Any way to measure audio bitrate outputted by software?

Hi,

I'm using audio streaming software which part of the fee paid is for a specific bitrate quality. Yet I'm getting the feeling that there's a large proportion of the media collection isn't available at this promised bitrate.

Is there any software I can use to accurately measure the bitrate of audio played back in real time?

Thanks.

Take a look at this BiteRate Calculator...

Hi,
Thanks for the suggestion, but that's simply a mathematical calculator. I understand the mathematics, that's not the problem. I want to actually measure the audio being played on the computer in real time.

Do you know of such a thing?

Thanks.

BitRate Changer Pro does exactly what it says it does but it will also tell you your current Bitrate on the audio.

Hi,

Is this based on having an actual file?

It's streaming audio, I don't have a file.

I need it to measure how many hundreds of thousands of bits of audio data are flowing per second...

Superior storage. Superior surveillance.

WD Purple drives are built for 24/7, always-on, high-definition security systems. With support for up to 8 hard drives and 32 cameras, WD Purple drives are optimized for surveillance.

Ahhhhh...ok, sorry about that, as far as I know I have not seen software that will perform this task. If I come across anything I will report back.

I don't believe there is any way to measure the bitrate because the bitrate is made up of hte sampling rate, bit depth and the number of channels. Unless the media player outputing the streaming audio specifically says under "Media Properties" or the like, I don't think it can be done when you're on the receiving end of the stream.

Perhaps you could grab a copy of the file and view the properties (like "Save A Copy" in Adobe Acrobat), but if you were to just record the file, the file you recorded would only have the bitrate at which you recorded it.

I thought as much.

Thanks for the confirmation.

I've just had a thought...

If I could measure the bandwidth that process is consuming, I could surely calculate the bitrate based on data required per second. Can you see any problems with this?

I did think of that too. And although you would be measuring the amount of data coming in, you still can't measure the bit depth or the sampling rate -- both of which have more to do with the sound quality than the number of bits coming down the pipe.
