first manual attempt?

Hey,

this is my first manual graph no bfd yet how does it look? awful I know.....

You could benefit from a BFD equalizer. I guess you already know that.

If you want an accurate measurement that makes the whole process so much easier, try out REW. Not many things come free these days... this one does...

Yeah i got a bfd dunno how it works?

do you have to use rew with a bfd?

this is it in a different position, which one is better?

BFD Guide - read me

do you have to use rew with a bfd?

REW Guide - read me

which one is better?

I don't really understand the question. Better for? equalizing, not equalizing......... They both require equalizing.

PhilB,

Unless you have the patience of a saint and would get some sort of perverse pleasure from setting up a BFD manually, then I strongly recommend using a PC with the REW software, together with MIDI capabilities.

If you have a desktop PC with a "gaming card" in which you could put a joystick, then the same port can be used for MIDI. Which is what I do. It saves ooodles of time and prevents premature alopecia!

If not you can get a USB MIDI connection. Or if you have a laptop then you will need an external soundcard anyway, so go for one with midi capabilities.

All IMHO!!

re-done with tones still no rew or bfd though..can u use rew with no spl?

[brucek]

can u use rew with no spl?

Don't understand the question..

brucek

do you have to have a spl connected to the computer to use rew?

[brucek]

do you have to have a spl connected to the computer to use rew?

I'm going to take a wild guess here and assume you mean the word 'microphone' when you say 'spl'.
SPL is an acronym for sound pressure level.

If you're asking whether you could use REW to chart external readings already obtained by some other means, then the answer is yes, if they're in the correct format.

I'll just print out the specific section in the REW HELP file I previously suggested reading.....
I have edited out things that may not pertain to you.

Importing Measurement Data

Frequency Response Text Files

File - Import Measurement command accepts text files in the following formats:

Cubic spline interpolation is used between sample points
Generic comma, TAB or space delimited files
Data must be presented as freq, SPL pairs, one pair per line
Samples can be at arbitrary frequency spacing, but each line must have a higher frequency than the one before and there must be at least 5 freq, spl data pairs
Only lines which begin with a number are imported, others are ignored
In comma-delimited files there must be at least one space after the comma
Spaces before values are ignored
To add a comment on a data line put a tab, comma or space after the spl value
Comma-delimited File Format
Here is an example of a valid format for comma-delimited data:

SPL measurements acquired by Room EQ Wizard V3.08
Source: D:\RoomEQ_Wizard\test files\testfile.txt
Format: Comma delimited data
Dated: 05-Mar-2005 17:53:56
Channel: Left, Bass limited 80Hz

20.0, 65.01
21.0, 65.77
22.0, 67.50
23.0, 67.93
24.0, 68.22
25.0, 67.88
26.0, 67.92
27.0, 68.31, this line has a comment
28.0, 69.14
29.0, 69.16
30.0, 69.29

If comma is used as the decimal delimiter in your locale it is best for clarity to use TAB or space as the separator.

Space-delimited File Format
Here is some data in space-delimited format
