Re: problem with huge lossless wma file

I'm very confused. How on earth did this file get created in the first place??

Have you tried using Aux. Input?

He did say it's from a radio station, a 6-hour radio show, so it's whatever the radio station used to encode it.

I was under the (probably mistaken) impression that a lot of radio stations actually use Real Media encoding, targeting multiple audiences, so the file is used for streaming, with has several bitrates running concurrently.

Right, the question is, how did the radio station encode it?

No, the first question is exactly what type of file it is. It is obvious it is not a regular .wma file, chances are it's not a .wma file at all, lossless or otherwise.

Then you worry about how it was encoded.

good point.

Re: problem with huge lossless wma file

The file's original extension is asf. When I run the mouse over it, this pops up:

Type: Windows Media Audio/Video file
Duration: 5:59:59
Bitrate: 1413kbps
Protected: No
Size: 3.55 GB

So the system can tell the correct length and bitrate of the file, but it just can't play it natively.

Open WIndows media Player > Tools > Options > File types . Is the format Windows Media File (asf) checked?

I think a possible problem is that it may be a multi-bitrate file, meant to be streamed from a streaming server.

Ok, I did some tests. The only way I managed to get such a bitrate and a file size that corresponds to an uncompressed 16-bit 44.1KHz stereo wav (i.e. 10MB/minute of audio) was to in fact start with a 24-bit 48Khz 2-channel stereo wav and encode it to wma lossless using VBR Quality 100 48Khz 2-channel 24-bit 1 pass VBR.

I don't have a problem playing the file in Windows Media Player 9. Of course, my file is only 1 minute long.

(Neil looks at Christina's last post ^^^) Haha one minute....of course. No one would ever make a 6 hour radio show....


Like I said before, I think the only solution is the Auxiliary Input the file to get another file out. And how was it ASF to begin with? :confused:
