That's a very good idea. Thanks. We'll definitely look into that. Some materials have always been part of the plan to offer separately, and some - possibly such as this - we knew may simply be requested once the videos were released.

Hi,

I've found an interactive version of the chart that shows frequency ranges for different instruments and some intresting added information that Alan introduced in the Eq video.

Here's the link:

Of course it would be nice to have a printable version of this to keep it hany in the studio, but this is a great start.

Hope this helps,

Hey Guys - great material. I've really been enjoying the series. You need to make a correction to your audible frequency range chart at approximately 5 minutes in though before this goes to disc. It shows the scale on the left starting at 30KHz, 50KHz, 100KHz and 500KHz which of course should really be expressed in Hz instead of KHz. Not even when I was 19 (or anyone else but the dogs for that matter) could I hear 30KHz. Ah the wonders of copy and paste.

Keep up the great work!

This may be beyond the scope of this series, however I was surprised to not hear any mention of how the electronics of an EQ device can and do affect the phasing of the frequencies being boosted or lowered through an EQ device. To effectively change the EQ of any frequency, introduces (depending on the quality of the device) slight changes in the phase of the frequencies due to the RC time constants of the electronic circuits that make up the EQ device. Individually this may not be noticeable, but as EQ's are "summed" or cascaded together in the audio chain, unwanted frequency boosts and cuts and distortion can become noticeable. Just thought it should have gotten a mention. In the radio broadcast industry, it is imperative to run a flat audio chain so the end user (the listener) can decide how they want to adjust the tone on their listening system. EQ in my field is a band-aid or tool to “flatten” the response of the system. The one area we can use EQ is in post production of say, a radio commercial. EQ can achieve many of the effects Alan mentions. Usually left in the hands of an unskilled ear, EQ is overused, used for the wrong reasons and then introduces artifacts in the process. Having the source audio as clean as possible to start with, is always the better way to go as Alan hinted in the series.

alf,

Thank you very much for posting the link. A really logical and very helpful website.

Thanks again!

bob katz book on mastering comes with a classic poster relating frequencies to instruments

I've really been enjoying the series.Thanks.

Luckily, I am here again as I thought I’ve lost everything. Now, I am pretty much happy to enjoy your new posts and marvelous ideas on the topics. Here my family is joining reading me.

Was good watching the series come through on and on.

They did a great job with the video. There is a lot to learn from this. Keep up the good work.

Really impressed! Everything is very open and very clear explanation of issues.
It contains truly information. Your website is very useful. Thanks for sharing. Looking forward to more!

Thank you for sharing the article . It let me know something I didn't know .I hope everyone here can find his or her dream ,then make it come true !

Hello, Nice website..Keep posting on good topics..i like art and science of sound.

i am as well trying to learn these tactics. The art of recording is quite different than we think

Cheers,

At the end of the EQ video, it mentions that there would be some documents at www.artandscienceofsound.com/files

I see some links there in the EQ section, but no other documents?

I agree. I think posting something like that online for us to be able to access would be much more convenient. Great thinking, Ken B!

I too am interested in obtaining the Comprehensive list mentioned at the end of the video.

Thank you to Alan and team for making such a wonderful, informative and helpful video.

I will look forward to these materials as they become available!

Hi everyone,
I just exported the list of frequencies mentioned at the end of 'EQ'. This is an animated video that was cut from the program because of size and duration constraints. We will provide a text/html version on www.artandscienceofsound.com/files in the near future.

Thanks for your patience,
Ben Cruz

Hi,
I recently checked the /files section and there's no text version of the EQ Settings as was promised for the "near future" in 2009 (see above).
Is there a chance that you will offer this text version soon?

greets

M.A.

Its really one of the nice forum related to music and its frequencies that the various graphs that you posted here.Thanks a lot for sharing this good info here.

Great post alf it is so useful to bear in mind that information everytime we are on a hands-on project!
