TDMS a formato WAV

Buenas tardes,
He grabado una señal de ruido con el sound and vibration Assistant. Ahora quiero pasarlo a un formato WAV (o similar) para poder escuchar lo que he grabado. He estado mirando por el foro pero no lo veo muy claro. Una vez tengo la señal grabada (formato TDMS), cómo puedo pasarlo a un archivo que me deje escucharlo?
Saludos
Aitor

Buenos días
Me da error al adjuntar el TDMS. Pero bueno, te digo los pasos que he seguido para grabar la señal con el micrófono
1. Add Step-->Acquire signal-->DAQmx acquire-->Analog Input-->Sound Pressure2. Grabo la señal temporalY ahora desde "playback" me gustaría pasar la señal que he grabado a formato *.wav Saludos

Sound in a Java App

Can anyone direct me on how to play an .AU audio file in a Java application? I know how to do this in a Java applet, but have had no luck with an application.

Hola a Todos.
Hace algun tiempo tuve el mismo problema y lo resolvi creando la siguiente clase utilizando el JDK1.3..
Esta recibe el nombre del archivo en el constructor (formato .wav o .au). y lo reproduce solo una vez.

Hi Dilpreet,
reading wav files is easy using the functions from the sounds palette...
For your other tasks you could use a seperate toolkit or do some programming on your own!

TDM Daten in Audio Wav wandeln

Hallo zusammen,
ich habe Daten von einem Beschleunigungsaufnehmer (als .tdm) die ich in Wav Datein wandeln möchte um die Signale hörbar zu machen. Geht das und wenn ja wie?
Thomas

Hallo Thomas!
Grundsätzlich sollte man jedes Signal hörbar machen können. Was man dann hört ist eine andere Frage. Ich selber habe dafür DIAdem nur zur Verrechnung der Daten verwendet. Für das 'hörbar' machen habe ich aus Faulheit das Open Source Programm 'Audacity' verwendet. Das geht sehr einfach wenn man eine TDM mit nur einem Kanal hat. Dann kann man in Audacity über Datei -> Import -> Rohdaten... direkt die zur TDM Datei gehörenden TDX Datei laden. Audacity erkennt das Binärformat dann automatisch richtig (64 bit float). Anschließend kann man es Abspielen, als WAV speichern und viel, viel mehr. Ob DIAdem irgendwie direkt WAV schreiben kann weiß ich einfach nicht.
Was ggf. notwendig ist und mit DIAdem sehr gut zu erledigen ist, ist die Vorbereitung der Daten. Sind dort Schwingungen vorhanden so muss man deren Frequenz in den hörbaren Bereich bringen. Dafür muss man bedenken das die typische Abspielfrequenz 44100 Samples pro Sekunde beträgt (CD Qualität). Daraus folgt das wenn die Eingangsdaten eine vollständige Schwingung in 44100 Messpunkten hat, der sich ergebende Ton 1Hz wäre. Das hört das menschliche Ohr nicht mehr. Auch der ungekehrte Fall kann zum Problem werden da die höchste Frequenz die halbe Abtastfrequenz ist, beträgt sie 22050Hz (Nyquist und Shannon grüßen) was auch die meisten Menschen nicht mehr hören können. Aufgabe ist es also die Eingangsdaten so zu verrechnen das nachher das Tonspektrum in einem Bereich von 100-10000Hz liegt. Im ersten Fall muss man dazu in DIAdem die Anzahl Datenpunkte verringern (reduzieren) im zweiten Fall erhöhen (interpolieren).
Etwas anders ist es wenn das Datensignal keine Schwingung enthält sonder dessen absoluten Wert hörbar sein soll. Das ist mit DIAdem recht einfach in dem man einen neuen Kanal über die Sinusfunktion berechnet. Aber auch hier muss man die Parameter so wählen das nachher was für den Menschen hörbares herauskommt.
Soweit erstmal ein paar Anregungen. Wenn dir mein Weg gefällt und was unklar geblieben ist einfach fragen.

How do you save arrays in tdm files?

Hi,
As part of a university project I am trying to save some program data to a .tdm file. On each channel I wanted a number of different types of data including an analogue wave form and a couple of 1-D DBL arrays. I have found an NI presentation that says that you can store arrays in them but dont seem to be having any luck. Any ideas what Im doing wrong? I am using labview 8.5.
Regards,
James

Hi James,
in a channel, you can save only one array as data. If you want to save more arrays then use several channels. You can organize them in groups. If the arrays must be in the same channel, then convert them to a spreadsheet string (in string palette) and save the string as a property.
Greetings,

Producer-Consumer, TDMS Log on Button

The program I've enclosed does what I need it to do quite well for the most part. I'm asking this question because I'm getting more data than I want and it's inconvenient to work with.
In short, I have a sytem setup to record pressure data from an explosion in a very short time period, the entire event is over in less than 100 ms, it typically occurs between 1 and 2 seconds after the ignition signal goes out. Therefore I want to record about 2 seconds of data total. The system has to run in a monitor mode for several minutes before any ignition while I fiddle with various elements associated with the experiment. It DOES NOT record during the monitoring phase but it must be running so I can fiddle with the experiment.
I think have two small issues that are increasing the size of my TDMS file.
When I hit the big red "STOP" button the system continues to record data for several seconds. I think it has something to do with the queue not being empty. It appears to be stopping at the correct relative time, but the data hasn't been streamed to disk yet. I can live with this but I suspect it's indicative of a bigger problem.
When I hit "Record" I have a 5s delay built in to engage a FLIR camera which has a variable startup delay (red circle in picture, record button not shown). This shouldn't get recorded because a "true" signal doesn't go to the record case (blue circle) until after the 5s has elapsed.
Example dataset below. To generate this data I started the VI and let it run for 30 seconds (I didn't have to let it run but that is more like a "real" test), after roughly 30 seconds I hit record and it started the 5 second countdown to ignition, I observed the ignition signal and waited to hit "stop" at roughly the 1 second mark on the count up. The VI continued to run until the timer read 8.32 seconds. The signals I recorded are just the TTL pulses that would normally go to my cameras, everything else is unplugged. Awyay, it looks like the system stopped acquirig data when I hit stop but the fact that it kept running tells me my queue didn't empty.
In the sample data the white line is the FLIR TTL signal. It lasts about 1 second (recording at 100 kHz), it should be a 1 second square pulse (or 100000 points), looks like the front got cut off. Sometimes it gets the whole pulse, sometimes it completely misses it. I think it has something to do with when I hit record relative to what is happening with the buffer.
The blue square wave that starts at 5 seconds is the 1/2 second TTL pulse that goes out to the high speed cameras and ignites the explosion. This is actually where the recording should start, where 0 seconds should be. I'm not certain why I'm getting the precursor data. In other words, all the data to the left of 500000 (5s) should not be recorded. The data ends just shy of 1/2 second (~50k points) after the blue pulse ends. This is right around the 1 second mark I tried to hit when I generated this data.
What is the result? Well, I'm recording 10 channels at 100 kHz so I end up with a 50 mb file instead of a 10 MB file and an extra 500k points that I have to strip off. This is tedious and time consuming, it really adds up considering I'll be doing this testing hundreds or thousands of times.
My questons. How do I delay recording until after that first delay is up? What am I missing? Is there some sort of a "TDMS clear queue"command?
Thanks for your time!

Skinnert,
Your program has many deficiencies that will make it very difficult to get your program to execute correctly. The architecture is linear and hard to follow its flow. Adding to the issues is the lack of wire labels and comments.
The program is flawed from the first step. You open 10 analog channels of DAQ but you are only saving a reference to the last channel opened. It may be working by some magic of LabVIEW but not recommended.
I would like to help out but there is just too much to take in to get a good answer. The goal of the forums to help people out. In your case you need to simplify the code and the question you post on the forums down to a paragraph or at most two. There is just too much for me to provide an answer. Ask a better question and you will get a better answer.

Logic 7.2 won't install TDM w/PT7

Hi there,
I just got my Logic 7.2 upgrade yesterday and it has two problems:
(1) Every time it loads TDM it crashes on one of the Waves Waveshells - I think it's 5.3 or 5.4. This same Waveshell loads fine when loading Pro Tools (7.1cs3). Removing this Waveshell allows Logic to at least load, though presumably without the functionality of the Waves plugs accessed by that shell.
(2) The whole TDM thing simply won't work in Logic. I keep getting an error saying that ESB cannot load. I did a seach and saw that someone had this same problem with Logic 7.1 and was told that Pro Tools needs to be installed first. In my case it obviously is, so the Logic installer should have seen and accommodated for that. Anyone know what's going on?

1) Yes, PT must be installed before Logic. If you're updating your rig, the PT update must be installed before your Logic update.
2) Logic TDM 7.2 requires PT 7.1cs4. 7.1cs3 will not work.
3) Most of your TDM plugins will have to be updated. Fortunately, most of them are available on one page at www.digidesign.com. The only exception we had was Sony Oxford, which required an $18 update.
4) Our Digi hardware configuration was all messed up after upgrading. You might want to write down how yours is set up right now. We forgot and had to experiment.
5) Repair permissions after installing PT 7.1cs4. Reboot. Repair permissions after installing Logic 7.2. Reboot. Repair permissions after installing all your TDM plug upgrades. Reboot.
6) I'm running 7.2 with PT 7.1cs4 and it's the most stable Logic's been for us since 4.7 on OS 8.6.
7) We're still using Waves 4.x with great success, so it may not be your Waves shell.

Error code -1 was returned by the Direct TDM driver

Everytime when I try to quit Logic I get the message "Error code -1 was returned by the Direct TDM driver". I can not quit Logic on the normal way, everytime I have to "force quit".
I use DAE and Direct TDM.
Any idea's how I can solve this problem?
G5 dual 2,7 Mac OS X (10.4.6) 4,5 GB RAM, Logic 7.2.1, PT7.1cs7, HD3 Accel, 192,2x96i, 96

I'v just received a mail from Waves:
The current OS-X 10.4.6 update causes problems with certain Waves plug-ins.
This happens when using the Mac automatic updates.
In order to fix it, please download Mac OS X 10.4.6 for PPC.
Install it and restart your computer.

Waves Tune plugin and os 10.4.6

I have a problem with Waves Tune. I installed 10.4.6, and now I always get the message "Error code -1 was returned by the direct TDM driver." Now I can not use my Waves Tune plugin anymore. It all worked fine in 10.4.5.
Any suggestions?

How to convert tdms to standard bin?

Is there any tool to convert tdms files into standard bin files? I would like to convert the tdms in a standard bin file to open and analyze it out of Labview. Converting the tdms to a sound file wave or aiff file would also work. Thank you.

mcas wrote:
Thank you. The "standard" bin format I need has to include one single header of 1 Bit and must be 16 bits. Is there any tool available to convert tdms to this bin format? thank you very much.
That means absolutely nothing. 1 bit of what? What does the 1 bit represent? 16 bits of what? What do the 16 bits represent? Are you saving values as 16-bit numbers? As I noted, there is no tool to convert TDMS files to bin files since the format is user-specific. You need to use the Write Binary FIle VIs to generate your binary file.

Schema (*.xsd) for TDM file format?

Our application (written in C#) has to...
- parse the TDM file for specific information
- edit the content of specific tags on the TDM file
We use the normal MS XML engines to process the xml information in the TDM.
Question: Is there an xml schema (*.xsd) available for the xml tags inside the TDM that we can use to...
- validate the TDM
- know which values are allowed inside the tags?
So far I found nothing that would help me during my two day cruise thru internet, zone.ni.com, Online-Help.
Thanx, Oliver Thost.

Hello Mr. Romainczyk,
Thanx for your reply to our post at zone.ni.com.
My Email: [email protected]
- We are NI customer in Germany.
- We bought DIAdem SSP contract to our new DIAdem 9 license.
- We also have bought LabView Developer Suite 1 year subscription.
- We program a LV application for PXI 8186 controller.
I also started a SSP technical query via telephone concerning the same topic but until now there is no answer.
In our project we need technical information concerning the TDM file format since we will develop an C# application that works with TDM files.
From the beginning:
1) Our LV application logs vibration measurement data (multiple channel) into multiple WAV-files that are referenced channels for the TDM.
2) So DI
Adem is able to directly read and process the WAV-data via TDM.
3) The third application (written in C#) has to read the TDM information and�
- delete one channel or
- change axis names or
- change samplerate for one channel or, or, or�
That�s why we are searching for a complete technical description of the TDM xml-schema:
- Description of all available tags
- Summary of all allowed data inside the tags
and so on
We already have the description for the DAT format.

Waves SSL Pack

Finished comparing these extremely great sounding plug-ins today.
We have an Analogue Desk (DDA AMR 24) which was made by the "old" SSL crew. The EQ's are pretty similar.
Anyway, these plugs are one of the best sounding music makers I've ever heard. Compression as well as EQ is ranking on my to 5 list.
In case someone should wanna try this adventure a downloadable demo is available at waves.com - u need an iLok though
Anyway, thought I'D share this

Hi - I use the TDM versions -
Channel Strip : 50 % of one HD Accel Chip
Waves GChannel : 77 % Of one HD Accel chip
I cant tell u usage with the AU's as I dont have the AU channelstrip....Anyway I guess It would be about the same....
IMO - if I should choose one over the other and also look at the price i'd choose the channel strip. It sounds very good but it is a plug where you should take a day to get to know it and apply it on verious application material. The Channel strip is one plug-in
The waves SSL pack are three plugs...so maybe thats where the diff. in price is...i dont know... I have both and both can be set to sound very similar...However, the possibilites of the Channel Strip are more diverse than that of the SSL Pack.
You have a incorporated Side chain on the gate and the compressor in addition to the EQ - which u can set pre/post of compression.

Conversor TDMS a txt

Buenas noches a la comunidad de NI!!
Bueno les queria realizar na pregunta y es co relacion a la conversion de archivos en el formato TDMS a txt. Estoy adquiriendo archivos de la tarjeta NI6356, tienen bastante cantidad de datos, sobre 1000 millones de datos a 2000 millones, por medio del programa que desaroolamos aqui en el foro en preguntas anteriores lo modifique para particionar el archivo el cual es de un tamaño aproximado de 1.27GB, para poderlo convertir, estoy empleando el archivo que adjunte al final de la pregunta. Hay posibilidades de lograr convertir un archivo formato TDMS a txt de éste tamaño?, o la unica solucion es como lo estoy trabajando? ..
Espero haber sido claro con la pregunta, estaré atento a cualquier sugerencia o ayuda muchas gracias a todos de antemano

Que tal Andres!!
Los archivos TDMS pueden ser abiertos directamente en MS Excel utilizando un Add-in Tool. En el siguiente link encontrarás información detallada sobre este tipo de formato binario, así como las ventajas que ofrece en cuanto a flexibilidad para ser utilizado desde otros programas.
http://www.ni.com/white-paper/3727/en
http://www.ni.com/white-paper/4906/en
Si te es posible, puedes abrir el archivo directamente en Excel y guardarlo como XLS. Sin embargo, si requieres un tab-delimited Text File para trabajarlo desde Matlab, puedes también abrir el archivo TDMS en Excel y guardarlo como un Tab Delimited. De esta manera, puedes guardar únicamente la pestaña que contiene los datos que te interesan, mas no las propiedades del archivo.
Esto te permite eliminar el tiempo de conversión desde LabVIEW para archivos sumamente grandes.
Te dejo también información sobre la limitante de tamaño para el manejo de archivos en LabVIEW:

TDMS oder TDM auf Kanal überprüfen ohne Datei zu laden

Hallo zusammen,
bin ein Neuling was DIAdem-Scripte angeht und bin auf ein Problem gestoßen, welches ich auch durch eine intensive Websuche nicht lösen konnte, vielleicht hat hier jemand einen Tip, wie ich das angehen könnte und ob es eine einfache Möglichkeit gibt?
Ich habe Messergebnisse in TDM- und TDMS-Dateien. In jeder Datei sind ein Haufen Gruppen und Kanäle vorhanden, ich benötige jedoch nur einen ganz kleinen Teil und möchte daher die benötigten Kanäle mit dem Befehl "DataFileLoadSel" laden. Das funktioniert soweit auch, jedoch habe ich nun das Problem, dass die zu ladenen Kanäle sich im Namen und auch in der Kanalnummer unterscheiden, d.h. ich kann diese weder im Namen noch in der Kanalnummer eindeutig ansprechen. Die möglichen Namen kenne ich.
Jetzt wollte ich diese möglichen Kanäle in ein Array schreiben und nun in einer Schleife prüfen, ob diese in der Datei vorhanden sind, ohne diese komplett ins DIAdem zu laden und im Anschluss den vorhandenen Namen nutzen, um die Datei zu laden. Und genau an dieser Prüfung scheitere ich, da ich bisher nur Möglichkeiten gefunden habe Kanäle zu prüfen, welche bereits ins DIAdem geladen wurden.
Ich habe mir erstmal beholfen, indem ich alle Möglichkeiten lade und den Fehler und Scriptabbruch durch nicht vorhandene Kanäle mit "on error resume next" abfange. Das ist natürlich extrem unschön und die Laufzeit meines Programms ist verhältnismäßig lang.
Daher meine Frage: Hat jemand einen Tip oder eine Möglichkeit, wie ich Kanäle in Dateien, welche nicht geladen wurde auf Existenz vor dem Laden überprüfen kann?
Viele Dank schonmal.
Gruß Gerd
Solved!
Go to Solution.

Okay, I think I have to explain my problem detailed that you understand what I'm doing.
I have a folder "D:\DIADEM_Auswertung\Auswertung_Daten". In this folder there are two diffrent folders called "Messung" and "Simulation" where are files created out of measurements in one folder and files created out of simulations in the other folder. Sometimes just one measurement file and one simulation file but probably sometimes more than one.
Now we have to compare the simulation and the measurement to find out if the measurement was okay. The problem now is, that the files out of the measurement contain a lot of data (goups and channels) which are not interesting for us. One file has about 500 mb. So I don't want to load the whole file but just the few channels we need. In addition in one file there are more than one measurement (4-6). This different data is stored in groups. So I have 4 to 6 groups in one file which i have to look through. Unfortunately this are not all the groups in the file and the group index is not always the same. Also the names of the channels and the index of the channels are not the same.
Now the task is to find the channels, load them, rename them, and probably change the unit or convert them to another unit. Furthermore I have to organize the loaded channels in Groups named after the files.
First of all I use the navigator to find my files in the folder "Messungen". For each one I call a function which loads all of my 10 channels if they are existing. Moreover I have a function call for each measurement in one file.
Afterwards I have to do the same with the files out the simulation but this is no problem because the channels are named always the same so I can load them directly.
Here is a bigger part of my code:
sub LoadData
i = 1
Rueckgabe = 0
For Each oResult In oResult.Elements
Richtung = "Beschl_Richtung 1 - Nord-Sued_01"
      Rueckgabe = Messung (i, Richtung, oResult)
      i=i+1-Rueckgabe
      Richtung = "Beschl_Richtung 1 - Nord-Sued_02"
      Rueckgabe = Messung (i, Richtung, oResult)
      i=i+1-Rueckgabe
end sub
function Messung (byval i, Richtung, oResult)
dim filenamePath : filenamePath = "D:\DIADEM_Auswertung\Auswertung_Daten\Messung\" & oResult.name
dim storeType : storeType = UCase(Right(filenamePath, (len(filenamePath) - inStrRev(filenamePath, "."))))
dim store : set store = navigator.ConnectDataStoreByParameter(storeType, filenamePath)
dim root : set root = store.RootElements(1)
if root.Children.Exists(Richtung) then
Dim KanalGeschFahr : KanalGeschFahr = Array("v_Fahrzeug", "GPS_Speed", "Geschwindikgeit")
Dim KanalBeschleunigung : KanalBeschleunigung = Array("GS2_Acceleration", "a_Fahrzeug_x", "Beschleunigung")
dim m
Call GroupCreate(left(oResult.name, inStrRev(oResult.name, ".")-1)& ": " & Richtung,i)
data.Root.ChannelGroups(left(oResult.name, inStrRev(oResult.name, ".")-1)& ": " & Richtung).Activate
dim group : set group = root.Children(Richtung)
for m=0 to ubound (KanalGeschFahr)
    if group.Children.Exists(KanalGeschFahr(m)) then
      'navigator.LoadData group.Children(KanalGeschFahr(m)), "Load" , nothing
      call DataFileLoadSel(filenamePath, storeType, Richtung & "/" & KanalGeschFahr(m), "Load")
      Call ChnPropSet(KanalGeschFahr(m),"unit_string", "km/h")
      Call ChnPropSet(KanalGeschFahr(m),"name", "GeschwindigkeitFahrzeug")
      exit for
    end if
next
for m=0 to ubound (KanalBeschleunigung)
    if group.Children.Exists(KanalBeschleunigung(m)) then
      call DataFileLoadSel(filenamePath, storeType, Richtung & "/" & KanalBeschleunigung(m), "Load")
      Call ChnPropSet(KanalBeschleunigung(m),"unit_string", "m/s")
      Call ChnPropSet(KanalBeschleunigung(m),"name", "Beschleunigung")
      exit for
    end if
next
if cno(left(oResult.name, inStrRev(oResult.name, ".")-1)& ": " & Richtung & "/GeschwindigkeitFahrzeug") = 0 _
    and cno(left(oResult.name, inStrRev(oResult.name, ".")-1)& ": " & Richtung & "/Beschleunigung") = 0 _
. then
      Messung="1"
else
      Messung="0"
end if
else
Messung="1"
end if
end function
Is that code okay in your opinion?
To your last question about the loading by DataFileLoadSel and the channel loaded using the datastore API:
The channels in the file out of the measurement are chanels in wave form. When I'm using the DataFileLoadSel the loaded channel is also in wave form, otherwise I use the channel loaded using the datastore API I get channels loaded in numeric form. I hope this is explained right. Here is also a picture where you probably see what I mean. The marked channels.

Auditioning wav loops at correct tempo

Hi Forum
I have been a Protools user for several years, but because of all the usual annoyances with PT I have decided to join the Logic camp, just today in fact.
However one feature I am immediately missing is the protools equivalent of "Calculate Elastic Analysis" in the workspace browser. If you are not familiar with PT, this enables you to preview wav loops at the correct tempo for your session.
In Logic I can navigate to my loops via the browser, but previewing them just plays the original tempo of the loop, not at the tempo of my session. I can of course drag it into the arrange window and fix it, but I miss the immediacy of the PT approach.
PT has a process called "Manual Indexing" that goes through all of your sample collection and extracts metadata such as tempo to make this process work. Is there perhaps an equivalent in Logic I haven't found yet? Do I have to convert all of my samples to Apple loops perhaps? but how would I do that?
Hope someone can help.
DH
