“though I use a stupid bitrate”

Are you talking 128kbit mp3 ? Started with that in 1998. Almost everything I have heard is fine at that rate.

I am sure that you are shocked to hear that iPhones can’t use those small, convenient SD cards for internal storage.

I do have a memory stick that uses the lightning adapter but its not what I am looking for.

Searching thru Apple support docs seems to point in the direction of my using a DRM-less encoding solution.


Way back in the 80’s I worked on a piece of software that would play back MP3s on the TI 99/4a. Discovered that Forth and Assembler could certainly do the trick, if I was patient enough. I wasn’t.

No. Most are @384 or so. Granted, when I'm on my motorcycle, or in my car, the higher bitrate doesn't matter much. You can hear the artifacts on the 128k files through the stereo at home though.

So what I am saying is in 1998. My DJ company was one of the first to play mp3 files from a p.c. Had to use 128k at that time. Only really had a 8 gig drive to work with. Each song was like 4 to 5 meg.
So 24 years later, sound is still fine. The original encoders might have been better with 128k than the current ones. I remember the name Fraunhofer-Gesellschaft (c) 1996-1997.

Up til then we were playing the CD-R discs that we recorded ourselves. Those first CD-R discs don’t play anymore as they have come apart on the surface.

Look into Audacity software to convert the files into something you can use. It’s free open source software.

I’m using it to digitize all my albums (over 1000). Well made application.

“PCM is pulse-code modulation, not pulse-width modulation”

You are correct.

Your hearing is gone!

MP3 encoding is MUCH better now than in 1998.

I work for a radio company and see the challenges involved in getting the best audio possible. Rarely do new releases come from CD. Most are d/l links from the labels or services like Play MPE or Promo Only. Legally we cannot use consumer download sites as those have personal use license vs a broadcast performance one.

The waveforms on nearly all files serviced have no dynamic range. The wav displays resemble two bricks. We generally drop these over 10db to get to -18/0 on a Dorrough meter. We always check the files in a spectrum analyzer and find many so called wav files are up converted from a lesser source.

It’s not the labels, but the producers and even artists. One major British act sent their label the wavs for a premiere, all rolled off in the same frequecy range as an Mp3. Throw in the digital codecs used stl to transmitter sites along with streaming codecs and you get can tell an mp3 source versus a true linear.

For older music we use cd but many time defaulted to the original releases due to the over processing of the remastered. It was more fun getting vinyl in the 70s at the stations.
