Hello Opus -

On one of the songs that I uploaded ("Shiny New Toys"), the bassline seems unusually buzzy. It's fine before I upload it, so it's most likely something in the conversion process. However, the same thing happens if I try to upload it to myspace, so it's probably something about the file that I need to change myself.

It's 44.1khz. I've tried it at 16 bit and 24 bit. I've tried it at 192 and 320kbps. I've got POWRdither type 2 on it when exporting.

If I download the mp3 from Opus it sounds fine (I can't seem to do it from myspace because their stupid servers are so wonky...). So it's something about being in a player...

advice is welcome! Hmm ...

Kirsten

Sounds Like A Flash Issue

Flash is not the best player in the world for MP3s. Unfortunately it is the most ubiquitous so we use it.

But let's try one more thing to make sure it is a Flash issue:
Try uploading a FLAC file.

If that is not working we will report a bug to Adobe.

Ah, technology

Ain't it grand?

I've uploaded 2 FLACs and if they work I'll redo the others too...

Thanks!

What is a FLAC?

I know mp3's and Ogg/Vorbis, but what exactly is a FLAC?

I had to look it up too

Free Lossless Audio Codec - basically a free & DRM-free open format.

http://flac.sourceforge.net/

You can download converters etc here: http://flac.sourceforge.net/download.html

Alas, that didn't seem to fix it.

The bass still has a bit of a buzz to it... sort of like a harpsichord overtone that isn't present in the original. Sad

I guess I'm just too bass-based for Flash...!

I'll send the files to Adobe please don't delete.

I figured that was the issue.

The Flash MP3 player is not the most robust. We will send the files to Adobe. Hopefully they can correct the issue in their next release.

That doesn't help you now, I know.

FLAC is the preferred upload

MP3s are really a vintage codec that is starting to show its age. It was part of MPEG 1 specification which is now over 15 years old.

If you can, a FLAC file is the preferred format. Since we are cross encoding to a variety of other formats, AAC, Ogg, MP3, and wmv (some day). A FLAC file enables us to ensure optimal quality across all these codec without re-encoding artifacts.

Since, music on Project Opus can be ported to any Website you want via the Opus Player and XSPF, our servers can be used as an archiving service for you. Uploading FLAC files is a good way for you to keep a pristine archive of your music. As new codecs are developed, Project Opus can transcode the files into the format of your choice.

I'll just delete the MP3 version so I don't have duplicates

and I think you guys will still have it on the server for a few days then. I'll try to remember to FLAC things from now on...

FLAC

So, if I'm thinking correctly, FLAC is similar to Ogg/Vorbis in that it really only serves the purpose when you convert from the original wav file?
Converting something from an mp3 to FLAC is pretty useless?

and thanks Kirsten!

FLAC is Lossless

FLAC is like AIFF except smaller.

No data is lost in the compression process.

MP3, AAC, Ogg, and wmv all are lossy codecs meaning data is lost as the audio files are compressed. So FLAC is a great archiving format for uploading to our servers.
