WXDX Using Higher Bit Rate

Wednesday, November 25th, 2009

08:00 PM: I was pleased tonight to learn that station WXDX FM in Pittsburgh has switched to a much higher bit rate on their Internet stream. Now, they’re streaming at 128 kbps instead of the 32 or 48 kbps they were using during the last hockey game that [Emmy] and I caught the other night. Hopefully this change-for-the-better is permanent and that more Internet stations will follow suit, including our favorites like KDKA, KQV, and KYW. It’d be nice if they all employed at least 128 kbps AAC transmissions. But I know, we’re still quite a ways from that utopia yet.

AAC Encoder License

Thursday, April 27th, 2006

Hi.

These were my thoughts too.

However, there’s an MP4 encoder I’m using (Apple’s QuickTime) that won’t allow me to encode audio files into MP4 without this license, even though I’m only encoding for personal use. But we’ve come up with a work-around, so this is not an issue currently.

 

Thanks so much for responding,

HD 650 Headphones

Tuesday, April 25th, 2006

Dear [Emmy],

All is good today. The guy paid me for the headphones this morning. So I took them to the post office. Nice sunny day today. I also sent out a check for the Stevia powder.

My contact in State College couldn’t find any info out about the Sennheiser HD-650 headphones I’m looking into buying. Apparently, his distributor doesn’t carry them. I’ll just buy one pair and see how they work. Then, we’ll just have to see about the others.

Yes, I like puttering with stuff around the house and fixing things. I even get a little thrill when changing a light bulb. :-)

Well, enjoy your day. Will talk to you tonight.

Super Audio CDs

Monday, April 17th, 2006

Dear [Mentat],

Well, I’d have to hear one of these to prove to myself that their fidelity is appreciably better than standard PCM CDs. But hey, I have an open mind. :-) At least the MP4 file format would support the extra audio channels in SuperAudio.

Electrostatic Headphones Need Power

Yes, I just tried them on a 50-watt amp. They worked much better. :-) At least now, I won’t have to build an amp for them.

Koss Tech 2 Headphones Mic Screw

Thursday, April 13th, 2006

Dear [Mentat],

That   mounting screw   you mention on the   Koss Tech 2   headphones was for mounting a microphone. I never saw the mic for them. But audio and video producers would use it to direct camera crews and such, while at the same time, listening to the program in their ears.  The Koss Tech 2 phones not only sounded fairly good, but they also offered versatility of us for a large array of studio and in-the-field directing applications.

Koss Tech 2 Headphones Remembered

Wednesday, April 12th, 2006

Dear [Mentat],

I just remembered them. They were the   Koss Tech 2 headphones.   Not much mention of them on the Internet but I did find a few references and auctions for them. They have been sold on eBay in the past but none are there currently.

Yes, it probably was Rich Parker who sold those to me. They really sounded good, or so I thought at the time.

Koss Tech 2 Headphones

Wednesday, April 12th, 2006

[Mentat],

By the way, do you remember way back in 1980? Either you or Richard Parker sold me this wonderful pair of   Koss Tech 2 Headphones?  I had them until 1991 when, finally, they fell apart, and now I’d like to find another pair.

The only problem is, I can’t remember the model number. Do you know it off-hand? They were a bit light on the base (which is normal for studio reference headphones actually) and the audio cable on each ear cane together into a Y just below the listener’s neck and from that point continued on as coiled cord to the quarter-inch stereo phone plug. I thought they might have been the Pro 4As but I found pictures on the Internet of this model and it doesn’t look like the ones I had. I hope you can remember them. :-)

Later.

AAC Encoding License

Thursday, March 23rd, 2006

There was a one-time administrative fee of roughly $15,000, which is determined by how many copies of the program I’d be selling to users. And then, you had to pay additional for each license. Since I would not be selling, they said they could reduce this fee to a few thousand. But that was still too steep for me. I requested a copy of their license agreement and fee schedule for exact numbers. We’ll see how it looks when it gets here. But it seems that they want their money, and lots of it. J I doubt they’ll be very sympathetic to a one-man development shop (like mine) that wants to use AAC strictly for their own purposes.

WAV to MP4 Export Issues

Wednesday, March 22nd, 2006

Yes, that’s right. I’m running Windows and wish to export AAC audio. I remember seeing this article, but figured that I could use the API since I have QuickTime Pro installed. Oh well. I suppose I can write a program to operate the Quicktime Pro UI in batch mode (I have many, many files to convert). I’ll look into the licensing however, and if it’s not too expensive, will go that route.

 

Thanks for the help,
