- Re-encode Files: Use an audio converter like Audacity or FFmpeg to re-encode the MP3 files. This process can sometimes fix playback issues.
- Update Software: Ensure your media player and any related software are up to date to avoid compatibility issues.
I used to use this cool thing called Agent-MP3. I cant find the place where I got it. Where is it?
Agent-MP3 is apparently gone. Agent-MP3 was merely another way to look at your own newsgroups on your own ISP's server. It could not do more for you than you could do with any decent news reader. The link to the site is dead.
What about Napster and other P2P services?
Napster was a very popular new way to acquire MP3s. The demise of Napster has brought a lot of new blood to the MP3 hierarchy (with a lot of habits that do not work well on Usenet). But most folks just moved to Kazaa or another P2P service (P2P = Peer-to-Peer).
The P2P services often have MP3s of distinctly inferior quality. As MP3s are being traded at an astounding rate, some files of very poor quality are being shared by more and more people. Many bad MP3s with pops, clicks, blips, jingles, gaps, blasts of noise, etc. are being posted to absm.*. No matter where you get your MP3s, please listen to all files with a critical ear before reposting to absm.*. If a file is audibly flawed with objectionable artifacts, please do not post it. A high bitrate does not automatically equate to high quality.
Playing MP3
So there's no way to just play my MP3s on a CD player, a Walkman or anything like that?
The technology is changing almost daily in this area. There are now MP3 Walkman-style players, built-in dashboard MP3 players for your car, mini-players that have headphones and port in to your home and car stereo AND your computer, and on and on.
How do I make a normal music CD from these MP3 files?
Some burner software will want you to first decompress your MP3 files into .wav files before creating an audio CD with your burner. But most newer software burns an audio CD without the intermediate step of creating a .wav file. Software packages that do direct MP3 to CD-R are:
Nero - http://www.ahead.de/
Roxio Easy CD Creator - http://www.roxio.com/en/products/ecdc/index.jhtml
WinOnCD - http://www.cequadrat.com/
AudioCD MP3 Studio (shareware) - http://products.pts-shop.de/
NTI CD Maker - http://www.ntius.com/default.asp
and many more. Check out: http://www.cdrecordingsoftware.com/
How do I decompress my MP3s into .wav files for burning a CD?
A number of software packages will do this, and are often referred to as "decoders". A good free one can be found at http://www.dbpoweramp.com/. You can look for "players" or "jukeboxes" at http://software.mp3.com/software/. Click the links for product type and select your operating system or platform. They also highlight only a few, so click around for a more detailed listing.
How do I use Winamp to make .wav files?
For whatever reason the creators of Winamp change its decoding function relatively frequently. Therefore, the following information may not be precisely accurate for the version of Winamp that you have, but it should be similar.
Start Winamp and hit Ctrl+P. This should open Win Amp's "Preferences" window. Now select the "Audio I/O" tab. Go down to the "Output Plug-ins" section and select "Nullsoft Disk Writer Plug-In"
Now when you "Play" your MP3 files, they will actually be converted to .wav files. (this information refers specifically to Winamp version 2.09).
DON'T forget to put your settings back to normal. You need to select an output of Nullsoft WaveOut Plug-In to be able to hear MP3s in Winamp again.
NOTE: If you use the EQ provided with Winamp, you might want to disable the EQ *before* decoding the songs to .wav. If you decode with the EQ enabled, the resulting .wav is NOT a clean decode of the MP3. It is a decode that has been EQed by your EQ settings. Perhaps this is what sounds best to you on your computer speakers, but if you're going to burn the resulting .wav to a CD for playing on a normal CD-Player, you might be disappointed by the 'tweaked' results.
Is WinAMP the only/best decoder?
No and no. WinAMP is very popular as a decoder because of its popularity as a player, but the links in will take you to some other decoders. When www.mp3bench.com was active it listed some interesting information about decoders and their bitrates. While WinAMP will decode at 32 or 64 bits, the venerable supposedly NAD decodes at 110 bits and reportedly delivers the highest quality .wav output. Download NAD093 at http://www.mp3-faq.org/downloads/downloads.html/ and see for yourself. CoolPlayer at http://www.daansystems.com/ is a popular freeware option for decoding.
I've got my .wav files; how do I burn a CD?
Burning a CD with your .wav files can be done using the built-in tools on Windows and macOS, or with third-party software. For Windows users, start by inserting a blank CD into your CD/DVD drive. Open File Explorer and locate the .wav files you want to burn. Select the files, right-click, and choose "Send to > DVD RW Drive (D:)". In the "Burn a Disc" dialog box, select "With a CD/DVD player" and click "Next". You will then see the "Burn a Disc" window where you should click "Drive Tools" in the toolbar, then "Finish burning" and follow the prompts to complete the process.
Mac users can follow a similar process by inserting a blank CD and opening Finder. Create a new folder on the Desktop and copy your .wav files into this folder. Once all files are copied, right-click the folder and choose "Burn [folder name] to Disc". Follow the prompts to burn the CD. This method uses the built-in capabilities of macOS to handle CD burning without the need for additional software.
Alternatively, you can use third-party software like iTunes, Windows Media Player, CDBurnerXP for Windows, or Burn for macOS. For instance, if you opt for CDBurnerXP on Windows, download and install the software from the official website. Open CDBurnerXP and select "Audio disc". Drag and drop your .wav files into the compilation window and click the "Burn" button, then follow the prompts to complete the burn process. For macOS, Burn is a simple and effective option. Download and install Burn from its official site, open it, and select the "Audio" tab. Drag your .wav files into the Burn window, click the "Burn" button, and follow the prompts to finalize your CD.
I burned a CD and there are pops between each track; what gives?
You should burn your music CDs disk-at-once, not track-at-once. Most popular CD-burning software offer this option. Take a look under preferences or options or consult the help file for your particular software package.
I was trying to record a live music CD, but there are pauses between each track. What can I do?
You should burn your music CDs disk-at-once, not track-at-once. Most popular CD-burning software offer this option. Take a look under preferences or options, or consult the help file for your particular software package. When you burn a music CD track-at-once, a 2-second gap is inserted between each track.
Also, apparently when you take a .wav file --> MP3 --> .wav file, there is a bit of silence inserted at the beginning of the final .wav that wasn't present in the original .wav. In order to make a truly seamless series of songs, some manipulation of the .wav files is necessary. Many audio software packages, like CoolEdit and SoundForge, will allow you to delete the silence.
In addition, MP3Cutter is a Win9x/NT program that allows you to chop up (and paste parts of) your MP3s without having to decode them to .wav. It is available at: http://home.hccnet.nl/p.luijer/.
Some people just combine every track into one large .wav file before burning it to their CD. However, if you do this you will have to edit your cuesheet to reflect a distinction between one song and the next
Do some CDs hold more than 74 minutes of music?
Certainly. You find 80-minute CDs everywhere. Just pay attention to the length and advertised recording speed. |
Downloading MP3
I'm using AOL and it's really difficult for me to get the MP3 files. Everything in the binary groups is a mess and out of order. Any advice?
Apparently you can use AOL's "Filegrabber" to only display binary files that are complete. AOL's newsreader can then automatically download and decode the file. You can accomplish this by selecting the newsgroup (e.g. a.b.s.m), clicking on Preferences, and checking the box that says "Show only complete binary files which AOL can download and decode. Hide text files."
There are times when AOL's software won't recognize that all of the parts are there. In these cases you may have to manually download each separate part and combine/decode them yourself.
ARGH! I don't like downloading with AOL's news software; can't I use Agent to get the files?
Yes and no. You can't use any external newsreader to access AOL's news server. On the other hand, you *can* subscribe to a stand-alone pay news server and use Agent, or any other newsreader, through your AOL internet connection.
It drives me crazy when the saved file attachment isn't named the same as the subject title! What to do?
If you are using Free Agent or Agent you have a solution at hand. Go to Groups | Default Properties on the main menu. Click on the Receive Files tab and check the box that says "Use the message subject for name of first attachment in message." This will save you a lot of time renaming later.
I can't use Agent at work. How can I download binaries with Netscape?
You have to save each part (number them!) with a .uue extension. It is a two-step process. After downloading, use Winzip to combine and convert from multipart .uue format to .mp3. Quite a pain, but it can be done. |
Making MP3s
How do I determine if my CD-ROM supports digital audio extraction (DAE)?
Some software packages will test your system for you. If you have Easy CD Creator, go to Tools|System Tests|Audio Extraction and run the test.
I know my CD-ROM does DAE, but I'm having strange problems and I can't get it to work right. What do I do?
If your CD-ROM supports Digital Audio Extraction (DAE) but you're experiencing issues, start by checking the CD and drive. Ensure the CD is clean and free of scratches or dirt, and try using a different CD to see if the problem persists. Confirm that the CD-ROM drive is functioning properly.
Updating drivers and firmware can resolve many issues. Make sure your CD-ROM drive's drivers are up-to-date via the Device Manager in Windows or System Information on macOS. Additionally, check the manufacturer’s website for any available firmware updates.
Switching to reliable software can help. If you're using Windows Media Player or iTunes and encountering problems, try Exact Audio Copy (EAC) for Windows or X Lossless Decoder (XLD) for macOS. These programs often offer better compatibility and performance.
Adjusting software settings can also make a difference. In EAC, configure the drive options to use Secure Mode and enable features like "Accurate Stream" and error correction. In iTunes, change the import settings to a different format and enable error correction.
Ensure your system has enough resources by closing unnecessary programs and restarting your computer. High CPU or memory usage can interfere with the ripping process. If possible, test the CD-ROM drive on another computer to determine if the issue is specific to your original setup.
My CD-ROM supports DAE; what do I use to rip audio tracks?
For users with a CD-ROM supporting Digital Audio Extraction (DAE), here are quick software options based on your operating system:
Windows:
- Windows Media Player: Insert your CD, open Windows Media Player, and click "Rip CD" to start. Adjust format and quality settings as needed.
- Exact Audio Copy (EAC): Download EAC, insert your CD, and use its secure ripping features for accurate results.
macOS:
- iTunes: Insert your CD, open iTunes (if available), and use its import feature to rip tracks. Adjust settings for format and quality.
- X Lossless Decoder (XLD): Download XLD, insert your CD, and choose format and quality settings before ripping.
Can I encode an MP3 straight off of the CD?
Yes, most encoders support simultaneous ripping and encoding.
I've ripped the audio track but the .wav file is messed up. It seems jittery and has pops or skips. Why?
Just because your CD-ROM is advertised to read at a certain speed doesn't mean that it can necessarily rip audio at that speed. Frequently jitter problems are directly related to the speed at which you're ripping audio. Set your software to a slower speed and try again.
Or you may just be having a software compatibility problem. Some ripping software doesn't work well with certain CD-ROM drives. Try using a different piece of software.
I don't like the way the song sounds on the CD because I like more bass. Should I adjust the equalization (EQ) on the .wav file before making it into an MP3 and uploading it?
Please don't. People generally want to hear an MP3 that is as close to the original CD as possible. Even though you may feel that something helpful (like normalizing the songs) will make them better, that decision should be left to the final recipient. If they want to tweak their MP3s, they can do it themselves. If you *have* tweaked or adjusted the song before you encoded it, please make that information known when you post it.
I've ripped the track to my hard drive. Anything I should do before I turn it into an MP3?
Yes. Listen to all of your files first. If you rip and encode to MP3 in two steps, make sure your source file is clean and doesn't have any jitter, skipping, distortion or unwanted noise.
Should mono material get encoded at the same bitrate as stereo material?
No. Mono originals only require HALF of the bitrate of a stereo recording to get the same quality. If you encode your Stereo MP3s at 128kbps, then the comparable Mono file would only need 64kbps.
For material with little high frequency content and waves with a 22050 sample rate, 64k is recommended. Some spoken word material with no special background effects can be recorded at a low bitrate without suffering loss of quality. Experiment with Joint Stereo, Mono, and VBR to get a good encode with a small resulting file size. Bottom line: do not waste server space or force long download times by recording at too high a bitrate if the source material does not need it, but do not destroy quality either.
What's the Difference between Stereo, Joint-Stereo and Dual-Channel?
Joint-Stereo - This method of encoding combines duplicate (or "perceptually similar") information from the Right and Left channels in an effort to most efficiently compress the file. This way the duplicate information is only encoded *once* instead of twice (one time for each channel) and allows for more bits to be allocated to the other non-duplicate information.
Dual-Channel - Two independent channels. This method keeps the Right and Left channel information completely separate. The downside is that if there is very little information on the Left channel, there is some "waste" of available bits that could be used by a very busy Right channel.
Stereo - Stereo does *not* combine similar information in the manner of Joint-Stereo, but it *does* use available or "leftover" bits from one channel to store information from the other channel if necessary. So it provides a compromise of the previous methods. Separate Right and Left Channels along with a somewhat efficient usage of the available bits.
No matter which type of encoding you use, please remember to listen to your files before uploading them.
