Myspace audio compression
Hi all,
I have recorded some material at a concert using a Zoom H-2, converted it to mp3 using lame at high quality, VBR with 160kbps on average. The sound could probably be improved, but I'm happy with it. Now I have uploaded the tunes to myspace. When listening through that Flash player, it is obvious that the highs above 12kHz are missing, I assume that happened during another audio format conversion by myspace. Do you know what's going on, and what I can do to avoid this? Lower bitrates? Boosted highs? Thanks for any hints, Boris |

MySpace converts it to whatever they use, which I suspect is whatever Adobe Flash uses. You might get an improvement by going for a higher bit rate to start with, but it will still be degraded by Myspace. Ultimately you are constrained by their file size limit in what you upload. -- Anahata ==//== 01638 720444 http://www.treewind.co.uk ==//== http://www.myspace.com/maryanahata |

Hm, maybe it get's better if I start with a LOWER file size, such that myspace thingy does not consider to do the recompression. Will try that... Boris |

Do you know what's going on, and what I can do to avoid this? Lower bitrates? Boosted highs? I can only guess, but I would suspect, that Myspace (as well as many other sites of that kind) converts the uploaded MP3 files to a proprietary format with a *fixed* relatively low bitrate. This makes streaming easier for them. Smaller files, all at the same bitrate - less traffic costs and they know, "what´s going out" for their audio streams. An interesting experiment could be to allow download of the song and then check out, which format the downloaded file has. Is it the same format and quality, that you uploaded it with? "Long" ago, the quality remained the same - but about a year or so ago, I noticed, the downloads were automatically squashed down to 96 kbps MP3. Seems like, this is not the case anymore. But what´s really going on there behind the scenes... I think, only the folks at Myspace could tell you for sure and I doubt, they want to tell you or anyone else outside their company. Lower bitrates will probably rather cut more highs, so this won´t help your problem. Boosting highs before uploading to Myspace might also not help, if the problem is really due to automatic conversion to a relatively low bitrate. In this case, the highs will get lost anyway, no matter how extremely they´re boosted before. The problem is a kind of "hi cut" filter caused by lower bitrate that you cannot control, which affects the sound. The best option is probably to regard is this way: streams are usually in the lowest acceptable quality to keep file sizes as small as possible. This is advantageous for flawless streaming even with slower connections. A stream, at least nowadays, will typically be of lower quality than a "full quality" download. When I listen to music on sites like Myspace, I don´t care about perfect sound quality. I´m interested in the character of the music then... If I like, what I hear, I start looking for options to find better quality recordings of this material. Phil |

Those sites aren't designed to distribute decent quality music. If you want good-sounding music down- loads, put your MP3 files up somewhere else and provide links on MySpace. |

Do you know what's going on, and what I can do to avoid this? Lower bitrates? Boosted highs? I went through this same exercise recently with my band's page. Myspace will check the file to see what the format is and convert as needed to meet their requirements, but the the result isn't good since it's starting with one compressed format and going to another, as you've discovered. The trick is to use a format that meets their requirements in the first place, so it's gets posted without conversion. What I came up with was MPEG1 format, no VBR, 128kbs stereo. You may be able to use a higher bitrate, but last I checked the Flash player doesn't support VBR at all. I use CD-EX with the LAME encoder to do the MP3 conversion, and it works great. Hope this helps, Sean |

That makes sense, thanks a lot! Boris |

If there is anyone else in this forum who posts music to MySpace, they have not identified themselves here. |

That was uploaded in 2007, though. Youtube might have lowered the bar since then. -- André Majorel URL:http://www.teaser.fr/~amajorel/ You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists -- Abbie Hoffman. |

Hi Sean, still no success. I have tried lame with the options -h -b 128, but on the myspace page it still sounds like before. Can you tell me what options you use for lame?

I don't use lame from the command line, so I don't know what the actual options are. I use CD-EX as a shell for lame (and a CD ripper,etc) http://cdexos.sourceforge.net/?q=download I use it with these exact options and it works every time: MPEG1 Stereo Quality=5 sample rate=44100 VBR disabled Just to make sure I'm not low-balling you on the sound quality, take a listen to my stuff - maybe what you're looking for is better than I've been using: http://www.myspace.com/redlineheroes It can be done, you just have to be persistant to find the right way. Hope this helps, Sean |
