FS#1899 - volume triggered recording

This closes feature request No 611717

Add a new menu item “trigger” to the recording menu. Once the trigger properties are defined you can arm the trigger by pressing play in the record screen.

There are some issues still to be fixed before this should be committed:

- When peak meter is in logarithmic mode the control of the trigger thresholds is lousy
- Configuration of the trigger can be saved in a config file, but not yet in rtc or anywhere else where the last settings are restored.

Wow! Thats very usefull for me. My dad is always wanting me
to record some of his old tapes to cd, and getting the
correct start is hard to estimate, and saves time in mp3
driect cut. Thanks Phil!

This new patch
- fixes the lousy db control issue
- settings are stored and restored
- prerecord time control added
- in recording screen the trigger setup can be opened with f3
- dropout time limited to max 2s
- response at start duration 0s improved
- unified some code

I consider it as code-police-ready.

This patch works great here. Also, nice to see you back
Phillipp! Maybe the time has come for configurable F menus
and other keys :D

Philipp Pertermann commented on 2004-01-04 03:37

Some changes as proposed by Martin Borus
- Thresholds limits adapted, special values have names like off, or -inf.
- Trigger modes renamed
- optical feedback on trigger states
- What about prerecording == record_pause? I turned on that orphant icon.

This patch not only closes the feature request 611717 as
stated above but closes feature request 882036 too (http:
func=detail&group_id=44306&atid=439121&aid=882036), which
is a perfect dupe. This goes very well with feature request 603469 (http:
func=detail&group_id=44306&atid=439121&aid=603469), which
requests a silence detection.

As the new Audio_3587 plugin requires a new build I would like
to include this in the Cyborg Systems branch of Rockbox.

Are you happy that it is finished now?


Philipp Pertermann commented on 2004-10-16 17:09

I updated the patch to match the current cvs. Still a few quirks in it :(


Philipp Pertermann commented on 2004-10-17 10:30

- retrigger seems to work
- led doesn’t blink in quickscreens

stupid me uploaded a broken patch file

Philipp Pertermann commented on 2004-10-27 08:13

synched with V2.3

Philipp Pertermann commented on 2004-10-27 08:41

Just because of the joy of it I uploaded a patch that
combines triggered recording with the recled patch 1055147.
It is more than a plain combination as changes in
recording.c were necessary. If someone agrees that both
(triggered recording _and_ recled) should be applied then I
recommend to use the patch file recledtrig.patch to make it

FYI: Documentation for this patch can be found on these two
sites: ecording

Philipp Pertermann commented on 2005-03-12 10:11

The new patch has a different display for the trigger states. It doesn’t use the traffic light symbol any more but something like a progress bar. It’s bigger and I had to sacrifice the display of the sample rate when recording from line in.
Maybe someone likes it.
