Is the sound recorded in DSLR Wav ?

I am curious about the format of sound recorded in DSLR - is it wav ?

I record sound via Tascam in Wav, but usually I also connect Tascam's headphone out via a splitter to my DSLR's mic input - The result is very clear DSLR Audio+Video ( DSLR gain set to 1 notch above minimum)

Is it fine to just use the DSLR audio in this case or better to use the Tascam wav file ?

Thanks in advance for your responses.

I tend to use the audio from the camera, set up as you have described above (although I use an attenuated splitter). This is by far the most convenient particularly if handing over footage for someone else to edit. The camera audio is included in the .mov file and wont be as good as that recorded on the Tascam (subject to what settings you use on the Tascam). But, depending on how the final product will be viewed you may not tell the difference. If in doubt, do both.

In the past, I did both and used Tascam recording - and in a couple of clips, I had to manually match up the sound as it wouldn't sync automatically - and that was painful (even with a clap) - thus I ask.

So i guess no one knows off the top of their minds whats the format of the sound baked into the .mov file in camera?

Well I always assumed it was a form of a .WAV file, but who knows? I don't think its a .MP3 file for sure, but its in bedded into the .mov and not really anything specific after that. Maybe a spec sheet on the camera might say something.

I asked this question recently and while the file obviously isn't a WAV file, it's apparently a full PCM file.. not lossy compression. This was regarding my T4i anyway..

Chas: Thanks for your response.

Dan: thanks for pointing me in that direction: A few searches on google found me this:

and since it appears that both (formats?) are lossless - I could safely go ahead with in-camera recording if its as clean as the recording made by external digital recorder

PCM = Pulse Code Modulated

PCM is the format of the actual audio data

WAV is a storage medium for audio data -- a file format. WAV files can
contain various data formats -- PCM being one of them.

Sound can be encoded in different formats. A few formats would be:
PCM, ADPCM, MP3, Ogg Vorbis, AMR-WB, etc. A .wav file can contain any
of these formats, but your software application(s) may only be able to
read certain formats.

"PCM" is the most basic format for the .wav file. PCM (pulse code
modulation) is time-quantized, amplitude-quantized, multi-bit digital
audio (e.g., 16-bit stereo samples, 44.1 kHz sample rate). Other
formats need to be "decoded" into PCM before you can play them on your
standard soundcard, and that is precisely where any specific audio
software application may come up short, i.e., it may not support all
formats possible in a .wav file.

Well if it is a PCM, that's good news, but what's not so good is that it's a 16bit/44.1K recording. While OK, better quality can be recorded on many hand held recorders. ZOOM, Tascam and others can record 24bit/48K which is the standard for broadcast quality. 24bit audio allows you more "headroom" if you will. Basically more dynamic range of the recording. It can take a stronger input signal before it breaks and distorts. While most people can't or won't know the difference if they were to listen to a 16bit audio file and then a 24bit audio file, it's just nicer to record at 24bit/48K rather than 16bit/44.1K. Mathematically there is a HUGE difference in the numbers, sonic, the untrained human ear usually can't tell the difference.

So the tascam should be set for 24/48 ?

Is all PCM 16/44? ....& what if the line out of tascam is fed into the mic in for 5DII ?

Thanks !
