Summary: ATSA errors

Initial Comment:
- analyzing with ATSA using the option File Type 4 produces this error:

Compiler arguments: [ -U atsa "H:\csound\manual\html\examples\beats.wav" "H:\csound\Analyses\beats.ats" ]
------- Compiler Start -------
PortMIDI real time MIDI plugin for Csound
PortAudio real-time audio module for Csound

0dBFS level = 32768.0
Csound version 5.11 (double samples) Oct 31 2009
libsndfile-1.0.20

Compiler Info/Warnings/Errors:

ERROR: cannot open file atsa_res.wav for writing


Also choosing another File Type, although an error is not reported, produces problems when trying to play back, for instance with ATSread.
See attachment.
The file is "beats.wav". I test on WindowsXP, Csound5.11 and WindXound

Message:
This looks like a file permission issue.   On Windows it uses a relative
name for the output (atsa_res.wav" whil eon OSX and Linux it ises
"/tmp/atsa_res.wav"

Could you have been in a directort (folder) to which you do not have write
access?

Message:
it is a windows thing. i analyzed "beats.wav" with the 4 different filter
settings and played them back with this:

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
; Audio out   Audio in    No messages
-odac           -iadc     -d   ;;;RT audio I/O

</CsOptions>
<CsInstruments>

; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1

ktime		line     0, p3, 2
asig	ATSaddnz  ktime, "J:atsawin_filter1.ats", 1, 24
; used 4 different filters

out	asig*10
endin


</CsInstruments>
<CsScore>
; Table #1, a sine wave.
f 1 0 16384 10 1
i 1 0 2 
e
</CsScore>
</CsoundSynthesizer>

The first 2 settings gave these results:
- ...contains no noise... error
The last 2 settings (3 and 4) gave no error but no sound, simply because no
noise was made by ATSA, at least, that is my opinion

Otherwise there are no differnces between the use of the ATS opcodes and
ATSA between Ubuntu and XP

Message:
Cannot reproduce this on Linux.  Is it a Windows file name problem?
