Possible bug in Opus 1.3 (opus-tools-0.2-opus-1.3)?
Hi!
Playing with Opus 1.3 I converted a tone sweep with a sample rate of 96kHz (just for fun). Before I had converted that from WAV to FLAC, and to Vorbis without problems.
With Opus I noticed that the file size for 48kHz and 48 kbps compared to 96kHz Vorbis at 31kbps is about double the size and it sounds even worse (than Vorbis) (there is a lot of noise in the lower frequencies when a low

Hi!
Excuse the delay, but I had to deal with a corrupted NTFS file system that ate many important files on an USB stick...
The FLAC version of the original is almost 6MB and it can be downloaded slowly from this time-limited link:

Vorbis for digital radio at low bitrates
Dear Vorbis Devteam,
My name is Michael Feilen and I've been working on Digital Radio Mondiale (DRM) transmitters and receivers for quite a while now. DRM uses HE-AACv2 by Dolby to encode the audio content (see http://www.drm.org/uploads/media/es_201980v030101p.pdf - pages 23 ff). As I think Vorbis is an excellent alternative, I'd like to implement and define an interface for Vorbis

Wireless Mic System
I have used several Shure systems, a few Sennheisers and a few
AudioTechnica systems.
Do not expect any of these systems, even the highest end, to be
anywhere as reliable as a wired mic. As the years went on, I
generally moved higher and higher end to try to weed out problems I
had with units that were due to design or unit flaws. I've been out
of the biz for a few years now (since my kids

Latency of Linux Bridge
Hi there!
I am working a lot with VoIP in my company, so I thought to use linux bridge functionality together with tc to emulate delay, jitter, packet loss, duplication, reordering etc. for testing purposes in our lab against our VoIP products.
I just recognized, that a basic bridge just with it''s minumum configuration of 2 network interfaces creates latency of approx. 5ms on very low

epoll increasing latency big time
Sorry this is going to be a bit vague, but I''ve noticed something rather odd
going on with EventMachine on Linux.
I''ve written something uses EventMachine to proxy HTTP to other processes.
On OS X, it works great, adding only about 20% extra latency into the
connection when proxying versus connecting to the original backend process
directly, so a 5ms connection might now take

Sennheiser is a reputable brand. The model you cited is in their lowest cost series. I have sold a number of these systems over the years. Their first generation (not G2) were problematic in not being very durable. I don't have as much experience with the G2, but the few we have sold have worked fine for several years.

Bandwidth and latency requirements
Hi all
I've googled but can't find an answer to my question.
I have two data centers. Currently, I have a replica (count of 2 plus
arbiter) in one data center but is used by both.
I want to change this to be a distributed replica across the two data
centers.
There is a 20Mbps pipe and approx 22 ms latency. Is this sufficient?
I really don't want to do the geo-replication in its

No Caller Name sent from Asterisk over Natio nal or DMS100 PRI to a Norstar MICS?
All good information, thanks. However this is private network between
Asterisk and a Norstar MICS about six feet away. So I'm holding both ends of

low pass filter frequency adjustable
Hi, recently I made some test with the opus tools (enc and dec) and I'm
very (and positively) surprised about the resultant quality. But the
only think that I miss is the ability to change the low pass filter
frequency via "--lowpass" option or similar. For example at a quality or
96 kbps the cut off of the filter starts at 16Khz and is completely cut
at 20 Khz. But in case of

My current issues is a 5 second delay for call that is being transferred

I am currently working on an Asterisk test system, and will be

The Asterisk system will be used to replace a Norstar MICS. The
location has two PRI's coming in, with a few hundred DIDs. I know how
to make * use the DIDs incoming, and I know how Nortel uses the DIDs.

Preparing music on hold
Greetings list,
I've been having a go at preparing some music on hold from CDs clients have supplied, but quality seems really rather poor over compressed channels (tried g729, GSM and Speex). I've been doing the following:

As I understand it, I'm reducing volume to 15% (which sounds about
