Re: Recording of a compressed Dolby Digital bitstream

What happens when you try? The only reason you need the file is to transport it from point A to point B for analyzing. If you captured the off-air bitstream, you wouldn't need the file -- or you wouldn't need the sound file. You could do that from your car in the parking lot -- or from the hotel at ...

Re: Recording of a compressed Dolby Digital bitstream

You know DAT machines speak AES/EBU. That's one of their "problems." People bought them for their extremely high quality audio only to discover that they only plugged into the AES/EBU audio routing switcher at the TV station. Many shows have been transferred to computers using the DAT head...

Re: Recording of a compressed Dolby Digital bitstream

That's a cousin to the problem that broadcasters have at the home. The stream has no beginning and no end. The job of the home receiver/DVR is to interrupt the stream and provide all the file headers and data management that computers expect. So you're not "saving" the sound. You need a st...

Re: Short time delay when recording

Two other notes: Every time you make a serious system change, restart Audacity for the changes to stick, and Macs do not support Hardware Playthrough.

Re: Short time delay when recording

Deep breaths. Please don't confuse monitoring your own real time performance with matching up your live performance with the one already on the disks. The later is latency and there is a tuner for that in Audacity -- although you will almost certainly want to fine tune it again later. The former is ...

Re: Flanger noise during recording

You can get other worldly special effects on recordings if you're recording the wrong thing. If you like to record internet music, you may have left Mix-Out running by accident. This means you're recording two slightly off versions of the same song with a brief delay in the middle. Windows Control P...

Re: How do I change the bitrates of many .mp3's at once?

A note that any time you change a compressed file it gets worse even if you stay in the same bitrate, and everybody's natural inclination is to "write over" the old files with the same filenames. That's fine if everything goes OK, but if it doesn't, you have no show and no good way to get ...

Re: Recording of a compressed Dolby Digital bitstream

Thereby avoiding having to buy a licensed Dolby® decoder. Not in Audacity. Especially in the 1.2 version, it's lucky to recognize AIFF, WAV and a handful of other formats. Dolby has a number of options and deriving the original show isn't for weaklings. We routinely fire up the Dolby generators not ...

Re: Buzzing Sound

<<<It has a constant buzzing sound>>>

Hope it is a constant sound. If it's not, the noise removal software will fail.
