I agree. I can analyse PDFs in Mathcad and the results are often very 
interesting.

Right. That is the sort of detail we really do need to be looking at, 
although I suspect that once the signal has the desired spectral shape 
it will be less of an issue. The differences between available pink 
noise generators is precisely why we are trying to reach consensus on a 
good standard.

I am not aware of any, although one would want to realize the signal 
with a commonly available smartphone or laptop class computer.

My personal view is that defining the ultimate pink noise signal is less 
important than agreeing on one that everyone can live with and adopt. Le 
mieux est l'ennemi du bien.

It is, indeed, in fact it's time after time proved impossible to change 
the words people speak. The best you can do is to get them to use the 
right words in writing.

A 'linear' response could be one that uniformly rises or falls at 60 
dB/octave!

Remember M G Scroggie's (Cathode Ray's) struggle to get people to say 
'non-linearity distortion' instead of 'non-linear distortion'. And 
people use 'linear distortion' when they mean 'non-flat frequency 
response', which is ipso facto NON-linear!

<PRE>Dear Thomas,

Thank you!

I have been struggling within '*a group with whom we
are liaising*' to get people to refer to flat frequency responses as
'flat', and not 'linear', but it is an uphill struggle.

People refer to 'non-linear frequency responses', for
example (when they mean a non-flat response), and the discussion then flies
off at tangents. What they are saying can be construed in two very
different ways. What '*linear response*' are they referring to? 'Linear'
does, indeed, refer to a straight line, but *non-linear acoustics* has
little to do with frequency responses.

We do need to clarify and standardise on the
terminology.

Best wishes,

Philip

<PRE>I wanted to alert the group to a response document which was uploaded today detailing the discussion of SMPTE TC-25CSS' sub group on Standard calibration reference pink noise to our liaison group AES 04-08 x216.

I'm afraid that between time zones and work conflicts, it is unlikely for me to be calling in to 04-08's Berlin meeting this weekend, but also wished to express our appreciation for your support and let it be known that we welcome any comments or suggestions that X216 may have.

Thank you and best regards

<PRE>Dear SC-04-08,

I received a few requests to be able to contribute remotely to this working-group's face-to-face meeting in Berlin. I am pleased to announce that we can provide a remote call-in facility for this meeting.

We will use GoToMeeting - a web conferencing service that is more convenient for this purpose than (for example) Skype.

While you are connected you will be able to hear the face-to-face meeting. Your GoToMeeting controls include a microphone mute - please consider muting your microphone unless you wish to speak, otherwise this meeting will be hearing your background noises and echoes throughout the meeting! Please note that the presenter controlling the projected image on the meeting's screen in Berlin is using a different laptop to the GoToMeeting host and so, although GoToMeeting offers a screen-share facility, we will not be able to offer this.

Please find below your login details.

When you call in you will be added automatically to the meeting. The meeting is scheduled to start at 11:00 Berlin time - please check how this corresponds to your local time.

Please note that this service is provided on a best-efforts basis - we can't guarantee the performance of the Internet! we are also limited to a maximum of 25 remote participants, so please understand if you are unable to get access.

regards,

Mark Yonge
AES Standards Manager

<PRE>Hi Mark
 The quality of the teleconference was very poor, and it meant that I could
not contribute at all to the meeting. Sometimes I missed out on whole
sentences.

I think the link was fine,; My experience tells me the problem was trying to
get a whole lot of voices in a reverberant room picked up by a microphone
that was miles from anyone, and a non-linear codec that does its best to
gurgle at the first opportunity it can get with a low level, reverberant
signal.

This is a much better way, but it will involve more microphones and a
discrete signal processor.

Hope it can get better next time...

Dear SC-04-08,

I received a few requests to be able to contribute remotely to this
working-group's face-to-face meeting in Berlin. I am pleased to announce
that we can provide a remote call-in facility for this meeting.

We will use GoToMeeting - a web conferencing service that is more convenient
for this purpose than (for example) Skype.

While you are connected you will be able to hear the face-to-face meeting.
Your GoToMeeting controls include a microphone mute - please consider muting
your microphone unless you wish to speak, otherwise this meeting will be
hearing your background noises and echoes throughout the meeting! Please
note that the presenter controlling the projected image on the meeting's
screen in Berlin is using a different laptop to the GoToMeeting host and so,
although GoToMeeting offers a screen-share facility, we will not be able to
offer this.

Please find below your login details.

When you call in you will be added automatically to the meeting. The meeting
is scheduled to start at 11:00 Berlin time - please check how this
corresponds to your local time.

Please note that this service is provided on a best-efforts basis - we can't
guarantee the performance of the Internet! we are also limited to a maximum
of 25 remote participants, so please understand if you are unable to get
access.

regards,

Mark Yonge

<PRE>Mark,

For some reason not known to me, I didn't receive any messages about the 
meeting in Berlin yesterday (27th) until today (I was busy for the last 
few days).

The last messages of any kind that I received from the group was 16th 
January, 2014 and then Peter Soper's message of 25th (last Friday).

I did know about the meeting from the Convention promotions and I 
certainly would not have been able to attend it, but I did expect to get 
some of the preliminaries in advance of the meeting.

It is possible that my yahoo email account has been marking them as 
spam. I have just checked and found only two recent SC-04-08 messages in 
there, but I don't know how often it clears it out.

It didn't used to do this. Up to January 16th I was certainly getting 
everything - so something changed.

Regards,

Bob
