MP3 Encoding with MediaSour

I've just recently ordered a pair of Super.Fi 5 Pro earbuds and while I'm waiting for them to arri've, I was thinking about the encoding of mp3s now. I have been normally using the MediaSource software to encode my CD ri
ps.
But I was wondering how all of you with high-end $200.00+ head phones felt about the quality of an mp3 encoded with MediaSource.
I'm currently using Sony's EX5L <EM>(I've had two pairs of these but the cord that goes around the neck seems to melt or get corroded over time exposing the stranded wires that form the actual wire on both pairs that I've owned, so I'm not going with Sony again)</EM>.
And I have been encoding with a Variable bitrate of 70% which usually produces an mp3 with a bitrate range of 2-60kb
ps.
At this bitrate the sound quality sounds decent on the EX5L, especially after some EAX adjustments on my Zen Xtra.
But is such a bit rate sufficient for higher-end earbuds? Should I use a different encoder?

I recommend Exact Audio Copy and LAME:
http://www.chrismyden.com/bestmp3guide.php
At alt_preset_standard, this will give you vbr mp3s at ~200 - 220 kb
ps.
Do some testing to see if you can tell a difference between these and your current mp3s when you get your new headphones.

Encoding Shoutcast mp3 streams with ogg vorbis

Hello friends,
I am somehow newbie to java and javasound.
Also i have intermediate English language skills, so please have some understanding.
I would like to create a java based project which part of it would be functionality similar to streamripper (http://streamripper.sourceforge.net/)
The biggest problem seems to be license fees for mp3 encoding.
I wonder if its possible to use mp3spi for decoding shoutcast streams and some ogg vorbis based encoder to save the stream into hard disk, splitting the files according to id3 tags.
Mp3 patents still apply?
Can be implemented with existing java technology? vorbisspi + mp3spi + Tritonus Ogg Vorbis Encoder + other?
Greetings

You might want to take a look at jicyshout
http://sourceforge.net/projects/jicyshout
It's basically an dead project that helps jmf read a Shoutcast stream. From there It's up to you how you want to save the stream. You might want to use an Effect to capture the stream in mp3 format and use the meta data listener in jicyshout to split it by song. There are bugs in it but it should give you a start.

MP3 encoder VBR Options doesn't work anymore

Hi everyone !
I always used iTunes mp3 encoder to rip my CD's with the VBR option ON and it worked fine until now.
Indeed since 10.3 the VBR option doesn't seem to be working no more : the output is a CBR mp3 file either I tick or not the VBR option box !
Does anyone have the same problem ? Is there a way to solve this issue ?
Thank you

We can't know. You have not provided any system info or other useful technical details.

ITunes 8 MP3 encoder produces different bitstreams under XP and Vista

Hello!
While organizing a new listening test for MP3 encoders at ~128 kbps VBR, I came across a significant problem in iTunes 8 and maybe older versions as well.
I have a 30 seconds sample file of Fatboy Slim's "Kalifornia" from the album "You've Come a Long Way Baby". The sample (as FLAC - you have to decode it to PCM WAV yourself) can be downloaded from the Hydrogenaudio Forums: http://www.hydrogenaudio.org/forums/index.php?showtopic=19682
If you encode this sample to MP3 using 112 kbps, VBR, highest quality, joint stereo under Windows Vista, the resulting file will have an average of 122 kbps. The same file encoded with the same settings and the same iTunes version under Windows XP will have an average of 191 kbps. I was able to reproduce this on three different machines with "clean" XP SP 3 and Vista SP 1 installations ("clean" means only the hardware drivers and all Windows updates are installed, no third-party software). It would be nice if other people could try to reproduce this if possible. Another interesting thing would be to see what the Mac version of iTunes produces.

By the way, iTunes is famous for having one of the worst MP3 encoders.

As3 mp3 encode problem

Hi,
We are developing an app that could play mp3s from a music store. We found that the downloaded mp3 from the store can't play be as3's Sound class. The file's information can be load, but just not to play. Same code (something like new Sound(); load(urlrequest);play();..) will work to some of other mp3s. I've searched from internet. Looks like this is only way to play mp3s by AS3. Some older AS2 code could play these mp3s by sound.loadSound(). I don't understand why the old method is better than the newer one, and it is in same flash editor and player. I re-encoded the mp3s by Adobe Media Encoder, and the AS3 player will work. But I can't do it for every customer's downloaded mp3. From internet, I can't find what is the specification of Flash friendly mp3 Encode. And every other mp3 player can play these mp3s even Flash AS2.
Please help!
Andy

The reason I listed as3 and as2 code with local mp3 is showing you even the code is simple like that, it is still not working. So I don't expect it could work with more complicated situation, and how wired it isthat AS2 code could work but not AS3.
It will be an iOS app, but anyway it will be running by swf, right?
The music will be downloaded from the music store, but it will be running in the local folder, not stream from internet.
So the code for music playing will just be like that:
import flash.media.*;
var snd:Sound = new Sound();
snd.load(new URLRequest("Music.mp3"));
snd.play();

HT1347 I have an mp3 DVD with episodes of Gunsmoke. iTunes imports them, but does not sort them correctly by date or episode. One file name is GS 52-04-26 001 Billy the Kid.mp3

I have an mp3 DVD with episodes of Gunsmoke. iTunes imports them, but does not sort them correctly by date or episode. One file name is GS 52-04-26 001 Billy the Kid.mp3. iTunes sorts them by month/day/year. How can I fix that?

The weird thing is, it worked before. I encoded all the videos previously and had them all listed and didn't encounter this problem, but I noticed I'd forgotten to decomb/detelecine the videos so I deleted everything and re-encoded it all. AFter filling the tags out and setting poster frames again I was thinking of making life easier by just pasting the same artwork for every episode, so I did, but didn't like the results so I deleted it again (I selected every video, used Get Info and pasted the artwork that way).
I think it was after this that the problem started to occur. In any case I've been through every episode and made sure the name, series, episode and episode id fields are all filled in with incremental values and they are. I even made sure the Sort Name field was filled in on every video. But this didn't work either.
So, thinking another restart was needed I deleted every video again. Re-encoded them all, again. Set the tags for every video and poster frame again. Finished it all off nicely, checked cover flow and was highly annoyed to find it was STILL showing the same two pieces of art work for every video as shown in that image I posted.
Ultimately, I wouldn't care so much that cover flow is screwing up like this as I always intended to sort by program anyway so it would only ever display one piece of artwork for an entire series of videos, however where-as when it was working it picked the artwork for the first episode of a series to display, its instead picking one of the latter episodes. I can't seem to find any way of choosing what artwork I want displayed.

Artifacts in mp3 encoding

I have been using itunes to encode audio recordings to mp3 for years but recently I have started to get artifacts appearing in the recordings. It looks like it is some kind of cross talk from one channel to the other (eg left to right) If there is speech on the left channel there is some faint twittering on the right. In the aiff version there is nothing, the twittering only appears after encoding to mp3. I usually encode to 128Kbps stereo. Any ideas on what is happening?

Is this truly something that has suddenly started happening or have you just started listening to tracks with true stereo isolation? Very few stereo recordings truly have all of one signal coming through one channel an nothing through the other.
In the mp3 encoder settings try toggling between joint stereo and normal. Part of mp3 space saving assumes that much of what is coming out one channel is similar to the what is coming out the other. It is redundant to preserve this separately so channels share some audio signal which can be stored jointly. I have zero familiarity with the encoding but am throwing out the suggestion that maybe in the case where you really have complete channel separation perhaps this joint method is allowing something to leak through to the other since it works on the principal that both channels do have similar information. "Normal" stores the two channels separately but also takes up more room because of redundant information storage.

New Drivers loose MP3 encoding.... You want me to pay for it

Hey,
Recently formatted my computer and reinstalled with the latest drivers for my sound card using the auto update service.
(Audigy 2 zs)
Was supprised to find the latest MediaSource 5 has lost the ability to encode MP3 Format. Was a bit bewildered to find that i'm supposed to pay extra?to have the privilage of having my MP3 encoding ability back.
Whats the story. This card was clearly sold as having this ability and now its been taken away and im told its got to be payed for to get it back. Just a?bit confused, sorry if this has already been posted.

To get the MP3 encode feature back. You need to install "Creative MediaSource Player/Organizer 3.30.2" software first which will add the MP3 encode feature. Then install the latest MediaSource 5 Player/Organizer software.
Next uninstall the "Creative MediaSource Player/Organizer 3.30.2" and the MP3 encode feature will remain in the latest MediaSource 5 Player/Organizer software.
The "Creative MediaSource Player/Organizer 3.30.2" software can be downloaded from the creative download webpage.
If you can't find the download, Follow these steps :
) Go to the creative support webpage.
2) Select "Sound Blaster".
3) Scroll down to the bottom of the webpage and select "If your product is not listed above, please click here".
4) Select your product "Audigy", "Audigy ZS" click next.
5) In the "manual selection" (on the bottom of the webpage), Select "Windows XP" click "Submit".
6) The "Creative MediaSource Player/Organizer 3.30.2" software will be listed under "Application" on page 2.
Goodluck!

MP3 Encoder Import Bitrate is not saved by ITunes

Hi!
The importing bit rate for the MP3 Encoder is not saved by ITunes.
This is obviously a bug only present in combination with special software / hardware, since several people have already have posted this problem on this forum.
I am running
- ITunes 6.0.1.3
- Windows XP Home Edition SP2
on a
HP Pavilion zd8000.
What I need to know is where these settings are stored, so that I can edit them directly to resolve the problem.
If this is not possible, how can I debug to find out what is going on?
I have reinstalled several times, and the system is not behaving consistently. I have played with different versions of ITunes. I have removed all ITunes entries in the registry between installations. I have succeeded in solving the problem, but it has reoccured.
Please advice.
Thanks in advance!

I solved the problem.
ITunes preferences are stored in a hidden directory here:
C:\Documents and Settings\Username\Programdata\Apple Computer\ITunes\iTunes.pref
(Programdata might be called something else in the English version of XP, I have the Norwegian version...)
Close ITunes.
Open this file in a text editor that can handle binary files, for example Textpad (www.textpad.com).
Remove the two lines starting with keys
iTunes.exe:MP3 Encoder:Custom
iTunes.exe:MP3 Encoder
Start ITunes. Set your desired import bitrate.
It should now be saved - and be picked up again next time you open your preferences.
Actually it was saved all the time, but something corrupts this file disabling ITunes from picking up the correct mp3 encoder settings. I guess the 160kb/s setting is the default showing up when no settings are present.
Hope this works for others having this problem as well!

ITuned mp3 Encoder Problem

Whenever I encode songs, I do so in mp3 format (very universal). I encode at 256 kpbs. However, one time I accidently did a 192 kbps encoding, but it sounded like a 112 kbps endcoding. Then I did a 112 kbps, and I was right. Then I brough up Nero so I could view the frequency range. it was worse than the 112 kbps... what is up with that. it cut off at about 12 khz on 192.... it cut off at about 12.5 or 13 khz with 112. Then I did a 256 encoding of the same song, and it cut off at about 15khz, which was about 128 kbps normally. Then I looked at previously encoded songs using this same iTunes that I just did (6.0.2.23), and at 256 they were fine, were normal. I did that one about 2 days ago. Then I viewed songs i imported yesterday. It had those bad effect tat it does now, cutting off at 16 khz and sounding like a 128 - 160 kbps. This has NEVER happened to me before on any otehr iTunes. I was wondering if this was a glitch or is fixed in the new 6.0.3 one that was released about 3 days ago. Thanks. I appreciate any feedback.

Logic/iTunes MP3 Encoder & Soundcheck Phenomenon

I'm noticing something weird happening when listening to either the CDs I import or the tracks I bounce from Logic on my iPod when soundcheck is enabled.
When I directly choose a song to listen to, the volume is decreased a whole lot, but if I choose the immediately previous song and click "next" or "skip track" into the song, it'll be blasting very loud. If I click "previous track" from the next song into it, it'll still play very soft. Now, I'm wondering why this is happening only with my iTunes imports and my bounces from Logic and not other tracks. They play loud and fine everywhere else (CDs, web players, etc). Is it a setting in Apple's Mp3 encoder? Can anyone help me understand what's going on with what seems to be sorcery? Thanks.

the only thing I can think of is the clicking "next" or "skip track" skips the ID3 tag for some reason, perhaps clicking skip or next purposely does not read from the beginning of the file so as to avoid a click or pop.
The Sonar w/LAME encoder does not include ID3 info so there's no normalization.
Another example of possibly doing a bit too much for the user. You don't want to use Sound Check anyway, why would you want everything at or close to the same volume?
Sound Check - Sound Check is a feature of iTunes, that can be used on the iPod, that normalizes the volume of the songs in your iTunes library. Because songs are recorded at different volumes and with different technologies over time, the volume that they play back at can be different. Sound Check scans your iTunes library and attempts to bring the volume of all songs in it into rough equivalence. It does this by scanning the playback volume of songs in the library and adjusting the "normalization information" ID3 tag for the song.
Sound Check does not actually change the volume of the orignal song.
Sound Check can be used with iPod playback as well. As long as it is enabled in iTunes, the Sound Check-enhanced songs will transfer to the iPod and play at a roughly equal volume.
Sound Check can be applied to MP3, AAC, WAV, and AIFF files.

Burn MP3 disk with correct stop time

I am trying to burn an MP3 disk with specific start and stop times. I can listen to it just fine on my computer, but the burn to MP3 options does not recognize the specific start/stop times. Any ideas?
Windows XP
Windows XP

iTunes > Preferences > Advanced > Importing > change "Import using" to mp3 encoder, and if required change the bitrate etc, in the "Setting" menu.
Now, in the main library window, select and ctrl-click on the track(s) you want to convert and you will see a "Covert selection to mp3" option.
The "Convert selection to ...." option will change depending on what format you have selected to import files as.
A warning though: AAC files converted to mp3s probably won't sound very nice!

MP3 Encoding using JMF

Hi all,
I was wondering if I anyone could give me some advice on how to change .wav files into .mp3 files using JMF. I've been trying to make Sun's Transcode program work ( from JMF Solutions ) but it keeps refusing to do that particular action, and complains about bad sampling rates.
Any help would be appreciated,
Vicki

In short, write a C++ class that calls a Linux MP3 encoder. Your java app passes the filename and the C++ class passes that to the encoder that then returns info about the encoding process to the C++ class that then passes it to the java class. You might even find a linux ecoder that works with java...Just hava a look on google or something
Could be tough.

How do I import files encoded with FFV1 into Premier CS5?

Sorry if I get things a little mixed up here, but I'm still a relative editing newbie and some terms are confusing to me, but here goes!
I've been given a bunch of short video clips that I need to import into Premier CS5. Trouble is, they have been (I am told) encoded with the FFV1 codec, and when I import them into Premier all I can see is the audio track and no video. Other than asking my friend to re-encode the files (over 200) in a different way, is there some workaround to get these files working in Premier?

JMF mp3 compatible with Flash?

Hi,
I am trying to convert some wav files to mp3 on the fly so as to allow streaming of the mp3 files using a flash player. However, I have noticed that the converted mp3 don't seem to be compatible with flash. Some of the essential details are as follows:
Input wav format: LINEAR, 8000.0 Hz, 16-bit, Mono, BigEndian, Signed
Output mp3 format: MPEGAUDIO, 22050.0 Hz, 16-bit, Stereo, BigEndian, Signed
Apart from the above mp3 format, I've also tried all the tweaking the sample rate, channels etc but none of the formats seem to be playing on the flash player. For conversion, I have tried using both the Transcode.java sample code as well as the JMStudio application provided with JMF installer. The mp3 files play out fine on other media players such as windows media player and on JMStudio as well.
When I try to use Audacity to convert the wav file to the same mp3 format as above, there is a difference of about 2kb in the size of the files converted using Audacity and JMF, the earlier being the larger one. The version of flash player that I am using is WIN 9,0,124,0.
Can someone please give an insight into what might be happening here. Thank you.

The MP3 plugin contains a decoder only. JMF does not support MP3 encoding.
