[Asterisk-Users] Playback Volume for Record Application
The Asterisk Demo prompts come through loud and clear on any phone that I use to call in on. When someone leaves me voicemail, it also comes through loud and clear. When I use the Record application and then use the recorded file in a Playback or Background application, it is very soft (clear, but the volume is cranked way down). This is true for all format types (I've tried wav, WAV and gsm). Also, from a number of different input devices (headset using an DIAX, real phone connected on the lan to *, etc.). Just curious whether there is anything I can do to improve the volume, other than recording the prompts in another application and dropping in the resulting files (it's obviously ultra-convenient to be able to change prompts just by dialing the correct extension) :-). ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I've not experienced the low volume when using record, but I have when using the record command in AGI. Upon looking around to see what it was that caused voicemail to be of such a passable volume, but not our AGI apps, I noticed that there is a section in format_wav.c that will bit shift the audio data up to increase volume. When I changed our application from recording in GSM to recording in WAV, it fixed some of our volume problems. Not necessarily a solution to your problem but a few data points to help sort the problem out. -- Steven Critchfield [EMAIL PROTECTED] ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] Playback Volume for Record Application
Thanks Steve. Right after I sent my note, it occurred to me that I could create a dummy voicemail account, and point my current Record extension to that, and use Voicemail to record the higher volume version. I just did one quick test, unscientific at best, and I think the above works reasonably well. Instead of leaving a message, I actually created a dummy vm user, and used VoicemailMain to record a busy.wav file, which I then moved to a normal sound file, and used the Playback application. It sounded enough louder to me than the original Record application made it.
