I've made squelch-1.0beta5 and uploaded it - you can find it linked from http://www.geoid.clara.net/rik/squelch.html This version has a config dialog. It works out which output drivers libao has available and gives you a choice. You can also tell it where your 'audio dir' is - though that works a bit strangely at the moment - when you change it, all the files you have in your playlist

Hi, I released Squelch 1.0beta9. It's a multi-platform Ogg Vorbis player, if you haven't heard of it. [1] Find it here: http://www.geoid.clara.net/rik/squelch.html Differences from beta8: * Vorbis comment editor ! [2] * More intelligent re-initialisation of output driver. * Stupid bugs in auto-update of master track list resolved. * Some bugs fixed, some more introduced ;) In theory,

I've written an Ogg Vorbis (only !) player, which some may like to play with. It works for me (tm) and I like it. If you don't, well, you know what you can do with it ;) I leave it running 24/7 and it plays my music without problems and without annoying me. That's all it's for, really. You can get it from http://www.geoid.clara.net/rik/arch/squelch.tar.gz The README follows ...

There are many ways to implement a VAD. What you described is actually perfectly equivalent to the most trivial (and least robust) VAD algorithm.

<ad> .q.u.e.l.c.h is an audio player dedicated to Ogg Vorbis. This is a bugfix release. RPMs available for i386, i486, i586, i686 and Athlon. Source available as tar.gz, tar.bz2 and src.rpm. http://www.geoid.clara.net/rik/squelch.html Tested on Linux, may work elsewhere. Requires only Vorbis, libao and Qt (compiled with thread support.) </ad> Have fun ;) Rik --- >8 ----

I decided to write a changelog for once. Here's the text for this release: * Fixed repaint of last column in master track list. * Turned radio buttons into combo box in config dialog, used Qt Designer to make it instead of hand-coding. * Now plays sample rates other than 44100 and channel count other than 2, so you can play 22050Hz monaural recordings if you're that

Hello vorbis, I'm chasing something to record the output of a radio scanner for long periods. It really needs to be able to split files (start a new output file every X MB), not record silence (the scanner sends no signal when there's no transmission, rather than sending static), and run under windows (because that's the requirement, ok). A command line app would be fine... Ideally it

I'm having trouble with the preprocessor's noise reduction feature. The basic issue is that it simply doesn't work very well. With my laptop (whose microphone is otherwise quite capable) I routinely hear transient background noise, typing, and other "quiet" sounds leaking through to the speex stream. Even worse, the AGC feature is blowing these things up into just awful

I meant "not knowing how speex's VAD works", of course, not VAD in general. If you would stop interpreting everything I say in the least charitable manner, this might be going more smoothly than it is. (Tom was right, by the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, When making a call like the one below, I get double DTMF tones on the PSTN side. DTMF tones sent from the PSTN arrives squelched on the SIP side. SIP > Asterisk2 > IAX2 > Asterisk1 > ZAP > PSTN SIP has been configured to use rfc2833 on both the SIP endpoint and the Asterisk. SIP endpoint also suggests a payload value of 101.

I've got a dumb Western Electric payphone and some homebuilt hardware to control the coin relay which is accessible to Asterisk through the AGI interface. I'd like to be able to set the state of the coin relay to collect at the end of a call if a called party answers. [Hey, I admit this project is being persued just for the fun of it ] Looking through the documentation, there is a way to

Hi I have a question regarding CTDB RecLockLatencyMs tunable parameter. Is there any relationship between the RecLockLatencyMs property and the RecoverInterval property? Does one need to be larger than the other? Or if RecLockLatencyMs were increased to 5000ms, should some other setting be changed in proportion? We're using a geo-distributed etcd cluster for the CTDB recovery lock and I

I also added a .desktop file for Gnome/KDE so that you can click on squelch from your panel etc. No icon right now - tmake doesn't support installing, so it's quite difficult to get that to work. Also I put a tiny script called 'squelch_wrapper' in the dist, which sets your LD_LIBRARY_PATH before running squelch - this way, you get the right Qt library loaded. Rik --- >8

hi all I'm being spammed by these messages in the console (see below) and sound doesn't work with today's cvs. I rolled back a week, and it works fine. In addition to the sound problems, I had to enable inband dtmf squelch on the dilnk mgcp phones. if not, each pressed key was counted twice NOTICE[245776]: File chan_mgcp.c, Line 710 (mgcp_rtp_read): MGCP ast_dsp_process

Hello Mark, The resulting 8 bit file has a lot of squelching noise compared to the 16 bit output from OPUS decoder. During encode I am using popi16fmtBuffer[ui32Loop] = (opus_int16)pcRdBuf[ui32Loop]; And during decode since the data is in the lower 8 bit I use pc8bitSamples[ui32Loop] = ((unsigned short)pcop16OutBuf[ui32Loop] ^ 0x80); Regards Amit On Sat, Jan 9, 2016 at 2:39 PM, Amit Ashara
