Loudtalks Cloud 1.2 and service pricing update

By Alexey Gavrilov on May 5, 2011

Today we have published a major update to Loudtalks Cloud client software — version 1.2.

Loudtalks Cloud client software version 1.2 has the following key differences from the previous 0.9.* releases:

  1. Reduced data usage and power consumption when idle. The new version uses 2.5 times less data while running in the background
  2. Faster status updates especially in the cases when one of the contacts lost network connectivity. With 1.2 detecting a client, which suddenly dropped off the network will take about 30 seconds — four times faster than before
  3. Improved reliability. We moved large portion of processing from the client to the cloud, which increases software stability and helps to address issues faster
  4. Compatibility with upcoming BlackBerry and Android releases

Important! The new version is not fully compatible with 0.9 releases (only communication via channels will work between 1.x and 0.9.x clients, direct communication between them is not possible), therefore it’s important to update the client software on all units in your network.

Changes in pricing
If you are using a premium service plan, your subscription plan monthly fee will not change. New customers pricing increases on average 50% starting today. You can check out updated Loudtalks Cloud prices here.

We are still offering a free service plan, which lets you use your private push-to-talk network for up to 10 users.

Loudtalks server API

By Alexey Gavrilov on January 29, 2010

We’ve made available to the developers the official Loudtalks server API. It works with Loudtalks Mesh and Loudtalks Cloud and allows you to manage users and channels from your application. Using server API together with Loudtalks SDK you can integrate our push-to-talk platform deep into your applications.

New in Loudtalks Cloud — dynamic channels & remote configuration

By Alexey Gavrilov on September 26, 2009

With Loudtalks Cloud update published yesterday we introduced two new features and numerous improvements, which worth some explanation. These are dynamic channels and clients remote configuration from the admin console.

Dynamic channels

Now when configuring a channel in the admin console, you can choose from using group channel and dynamic channel.

Dynamic channels have a different icon and work differently too.

  1. Unlike group channels, when you add it to the user, only that channel (and not its users) is added to user’s contacts
  2. You can connect and disconnect the channel from the client software in real time by double-click (tap) on the channel name. That way you can easily skip the conversations, which are not relevant at the moment
  3. Since dynamic channels don’t “pollute” your contact list, they could potentially scale well beyond 100 users per channel so you can use it for broadcast to really large groups of users which was impossible before.

Along with the introduction of dynamic channels concept the group channels operations was also seriously redesigned. Both group and dynamic channels now include the following features:

  1. For messages received from a channel, the channel name along with sender name appear in the notification window (only user name appeared previously)
  2. Channels now have their own history display
  3. When the new message is received from a channel after a period of inactivity (“new conversation” event), the channel is selected in the contacts instead of a user
  4. Call setup time for one-to-many calls is faster than before and consistently under 1 second
  5. There is a grace time of 10 seconds for every message sent to the channel. During that time the person speaking couldn’t be interrupted. That solves the issue when many people start speaking simultaneously but still allows to interrupt someone, who took over the channel for too long.

Clients remote configuration

If you are running a large network, you may face the problem of manual configuration of every device, which could be troublesome. With remote configuration feature the network admin can setup certain client options for all users right from the web console.

Right now we enabled the configuration of automatic updates, auto-away and voice quality.

Voice quality configuration wasn’t available before and now you can select one of standard profiles or go real hardcore and modify raw codec options. This might be especially useful if you are using Loudtalks over the satellite internet (where traffic is extremely expensive).

If you haven’t tried Loudtalks Cloud yet, go ahead and try it now. It’s free!

What lightweight means

By Alexey Gavrilov on August 6, 2009

We say that Loudtalks is lightweight, but what does it actually mean?

Here is a little test.

1. Take a 5 years old laptop with 1.7 GHz CPU

2. Launch 21 (yes, that’s twenty one) copies of Loudtalks Mesh client on it

3. Launch  Loudtalks Mesh server on the same laptop (!) under VMWare

4. Test one to many messaging from the first client to 20 others

Here is how that looks:

The cpu load fluctuates in the 50..85% range and everything works nicely.

The same codebase is used on mobile devices, which allows Loudtalks enabling push-to-talk on the old Windows Mobile communicators with 200 MHz cpu and consume less power on the modern ones.

Status update

By Alexey Gavrilov on September 11, 2008

Next week (September 18) we celebrate Loudtalks first anniversary so I thought I’d give a short update on what’s going on.


  1. Loudtalks release. The release will introduce the major improvements in sound quality under poor network conditions like 2G wireless (EDGE) or crowded WiFi. It will also include additional optional notification sounds (beep on any new message, roger beep, ready tone), which are useful for “blind” professional use
  2. Loudtalks for Windows Mobile work has been freezed temporarily, we plan to release it initially as a part of enterprise offering (see below) and later as a free consumer version
  3. We’ve released Loudtalks Mesh — the enterprise product, which allows you to deploy a private Loudtalks network at your organization. It includes a pretty ajax-driven server admin console. See the slideshow embedded below
