Sorry guys for my question as I can help your development only with PayPal...

I was going to buy a 600D but as there is no audio monitoring during recording I'd go back to 550D but your post gave me hope...
So... when do you think that a quite stable version could be released?


Probably will be merged for next version. A1ex is doing 5dIII stuff. Audio works pretty well. Miyake's bin is almost vanilla 2.3 + audio. If you have a 600D still you can try it.


Today I came back from a 4 weeks filming session for a documentary.I used the normal 2.3ML without the features you added because I had to be sure that everything works. In this time I had one day to test 0.5 Alpha release of ML for 600d with audio enabled and I really liked it.
Now after having my 4 weeks praxis test I really like to have one feature: controling the mic gain while recording. This feature is essential especially for documentaries. I can't set up my camera befor recording. Everything has to be set while filming. So what's about changing the gain with the wheel while pressing Q? Would be a great feature for the ML-600d-audio version.


Now DISP shortcut key is controlling only analog gain. So you want to change mic boost like analog gain shortcut , right?
And it's enough?

I think , current shorcut key is controlling monitoring volume too. If I change shortcut vertical line to mic gain controlling, it's a enough for you?
Or , replace horizontal (analog gain) to mic gain control. Is it enough?

However, a lot of user using, sound functions. It's need a more considerations.


Oh I did not know that its possible to contol audio with the DISP-button. So This will work only with audio control by ML? Like I said, I used the "normal" 2.3 ML firmware with my 600d and there is no audio-support for 600d. I thought of controlling the canon manual audio control with magic lantern. but now I think I don't need it any more. (sorry: hard to describe, I am not a native english speaker)


Never mid, I'm not native too.
Anyway, Try our 600D audio 0.11 version. And If you find bug or had a some advice to us, feel free to comment to this forum.


I thought you could change everything on the fly from the menus.


Merged all of our 600D audio codes to unified development tree!!!
Those codes are leave from our hand. Thankyou very much all testers. It's our developers/testers achievement.
But if you found some more problems, I can support you and if I found/solve bugs, I can push bug fix code to Alex.
Next release or improvement .bin will release from core team. 


Thanks @Miyake, @1%, and all developers for your effort! Working audio on 600D is amazing!
Thanks Thanks Thanks!

Hi, great news and thanks.
Is this functionality now merged into the main 2.3 download - if not any idea when, and what is the best way to download it currently?


The 2.3 is frozen. The functionality is included in the source repository so you'll have to compile it yourself
EOS 1100D | EOS 650 (No, I didn't forget the D) | Ye Olde Canon EF Lenses ('87): 50 f/1.8 - 28 f/2.8 - 70-210 f/4 | EF-S 18-55 f/3.5-5.6 | Metz 36 AF-5


Thanks a lot for this realy good work  ;D

Is it possible to  just have a 600D audio 0.12 version without the "test" message?
I really don't know how do it myself  :-\
Sorry for my English ^_^


Good work! Thank! Join request the release of version 0.12 of the test without a message about test.


Test version are NOT released without the Test advice to avoid confusion with official release.
Only if you compile it by yourself you can edit makefile.user to remove it

I'm using ML2.3 for photography with:
EOS 600DML | EOS 400Dplus | EOS 5D MLbeta5- EF 100mm f/2.8 USM Macro  - EF-S 17-85mm f4-5.6 IS USM - EF 70-200mm f/4 L USM - 580EXII - OsX, PS, LR, RawTherapee, LightZone -no video experience-

Mister Paul


first of all thank you very much for your great work. It's so helpful.

I tried it on my new 600D. Sorry but I can't compare as I don't have any 550D or other DSLR. And I am new to Magic Lantern too...

I have 2 points to mention:

1° As expected I get audio monitoring in my headphones during recording, but I don't get any sound in them during playback:
only the Canon speakers are playing the audio tracks even if my headphones are plugged (and recognized by ML)
Not sure if I have misunderstood something (I suppose!) or if that's a bug...

2° I am not sure to have best settings in ML for recording/monitoring for my Rode VideoMic Pro (output impedance = 200 Ohms)

- My Rode settings: +20db increased signal level + High Pass Filter on
- Magic Lantern settings:
Analog Volumes: 0db
Digital Gain: 0db
Output volume: 0db

In fact my settings are only controlled by using the button DISP. shortcut for analog gain (horizontal) to set "Input vol" at +15db or +24db
I see better modulation at 24db but I get some more hiss too (in my headphones but not recorded)...
Also I supposed that these settings should be seen after on menu "Analog Volumes" but it's still set to 0db

Do you think am I wrong in my way of managing the settings or I could get better results with another approach?

Thanks for your help


Playback isn't set up to work through headphones.

QuoteI see better modulation at 24db but I get some more hiss too (in my headphones but not recorded)

In my case the hiss seems recorded but I do think monitoring is off from recorded audio. I think that's a problem with the IC though. Thanks for testing.

Ok, Ok no problems to wait the official 2.4   8)
Sorry for my English ^_^

But just to ask more precisely, do you think that it's better to adjust recording levels:
  - using DISP shortcut (step by 9db - jumps from 15 to 24db...)
  - "Analog Volumes" from ML Audio menu (step by 5db)
I suppose we interfere on the very same parameter (analog gain) with both, no?

Playback isn't set up to work through headphones.
Would be great to control taken shots!


Can't really play back the movies in camera, would be nice just for wav playback since I have them recording separately. Its like internal w/external channel swapping, nice but effort < result.


could it be that the download link isn't working.

i wanted to test the audio test version.



sorry but i don't know which file i have to download for the last audio test release 0.11 or 0.12 ?

is there a official release date for next ml version?

thx maz


The test releases are gone. You can either compile ML from source or use my binary. Sorry. :(

Mister Paul

I just found something weird... I don't know if that's related specially to the 600D Audio release or if it would have been the same with others Canon devices:
I was recording a movie with external mic + earphones: OK.
I took a photo during video shooting: OK.
But when video came back after the photo:
- 1° the sound was saturated (levels up in red),
- 2° No more audio monitoring (but the movie was still recording),
- 3° I had to shut down the Canon (On/Off or releasing battery) to be able to use ML or Canon menu again.

Effectively when I read the .mov after the sound level jumps high (saturation)
