SLP  Update: SSO login & Speaker dimming for Dubbing

With the latest updates, SSO login has been integrated for all products and a speaker dimming function has been added to SessionLinKPRO | Dubbing!

SSO login

It is now possible to log in to all of our products using a SAML based SSO authentication flow. The authentication flow should work with all major SSO Identity Providers. SSO can be configured in the “Security settings” section of the account management.

Speaker dimming for SessionLinkPRO | Dubbing

We have added a speaker dimming option to the guest instance of SessionLinkPRO | Dubbing to further prevent unwanted echoes and feedback loops. When active, the guest’s speakers are dimmed as soon as the mic is opened in push-to-talk mode.

SLP  New product online: SessionLinkPRO | Podcasting

Our latest product SessionLinkPRO | Podcasting is now available!

We took the feedback from many customers and put in into the development of an application specifically tailored for remote podcast recording. SessionLinkPRO | Podcasting enables easy recording of up to 4 participants (host + 3 guests) directly in the browser. A separate audio track for each participant guarantees professional post-processing.

But of course that’s not all:

The guest page has been designed to be as user-friendly as possible and can be used with Chromium-based browsers, Firefox and Safari. Mobile use via Chrome for Android or iOS Safari is also possible.

SessionLinkPRO | Podcasting can store multiple recordings that are accessible through the built-in file browser.

The most important settings are all made by the host, so that even inexperienced guests can take part in a recording.

There are advanced routing options for professional users, with which the received signals can also be routed to separate audio outputs.

And of course, as with all SessionLinkPRO products, it also works with our usual high audio quality.

SLP  New versions of all products online!

As of today (February 27, 2022) the new versions of our products are online. Aside from some under-the-hood tweaks, we’re excited to announce the new “Mono L16” option for SessionLinkPRO | Recording and SessionLinkPRO | Dubbing.

With “Mono L16”, SessionLinkPRO | Recording and SessionLinkPRO | Dubbing now offer the option of unencoded 16-bit PCM transmission in mono in addition to the well proven transmission with the OPUS codec.

At SessionLinkPRO | Recording, the maximum stereo bit rate in OPUS mode has been increased to 510 kbit/s.

In addition, we have accelerated the program start in SessionLinkPRO | Video, SessionLinkPRO | Conferening and SessionLinkPRO | Dubbing by improving the initialization of the video devices.

We have optimized the handling of disconnections for all products.

SLP  Update for SessionLinkPRO | Dubbing

Today we released an update for SessionLinkPRO | Dubbing. The following features have been added or changed:

  • L/R split mode: In response to popular requests, we have added a second L/R split mode. The new option “L/R split (direct disabled)” works without a direct connection between the Actor channel and the Director channels to allow more flexible routings.

  • Video overlay (watermark): The position of the video overlay is now configurable. You can position the video overlay by drag&dropping it to either the top, bottom, left or right.

  • Onscreen recording light: The new onscreen recording light can be triggered via MIDI controller data.

  • Remote controlled recording: The host now determines the settings for preroll. A corresponding checkbox can be found in the “MTC / Video Matrix”. The choices on the guest side are reduced to a single “Record Control” option.

Further information can be found in the new version of our quick start guide.

    SLP  Information regarding the current COVID-19 situation

    As you can probably imagine, we are getting lots of requests for free trial accounts at the moment. To ensure that our resources will be able to handle the increasing load, we have scaled up our server network and are constantly monitoring our servers. However, we have decided to shorten the free trial period to 7 days. Trial accounts cause the same load to our servers as paid accounts do and we have to make sure that our paying customers do not experience a shortage in our resources. We hope for your understanding! Your SessionLinkPRO team

    SLP  New versions online

    Maybe you already have noticed: new versions of our products are online since 03/17/2019. Here is an overview of the changes:

    SessionLinkPRO | Recording:

    • By popular request, we have added a new routing option to the “dual mono” mode. If activated, “bridged” allows the two guests to communicate with each other. Full signal separation at the host is preserved for recording both guests on dedicated channels.

    • The “Record” feature now allows to record both, local and remote signals, at once. Of course with full signal separation.

    SessionLinkPRO | Conferencing:

    • Again, a popular user request turned into a new feature: we have added a group chat.

    • The SIP client now comes with an additional dial pad. For example, it comes handy if you need to enter a pin code for a phone conference.

    SessionLinkPRO | Conferencing + SessionLinkPRO | Video:
    We have added Firefox support for SessionLinkPRO | Conferencing and SessionLinkPRO | Video. Please note: this feature is in beta test, so no guarantee!

    SLP  Updates for all products online

    Today, we have released updated versions for all products. Besides some changes under the hood, we’ve added some new features:

    All products:
    A new button is available to toggle IPv6 support. This was necessary to prevent connection issues with IPv6 tunneling on a couple of routers. IPv6 tunneling may lead to major connection issues resulting in heavy drop outs and glitches.

    SessionLinkPRO | Recording / SessionLinkPRO | Conferencing:
    You now have acces to a connection log. The connection log keeps track of connect and disconnect events and can be used to determine a session length. For increased privacy, the log is stored on the local computer only and will be deleted on log out or when the browser is closed.

    SessionLinkPRO | Recording:
    We’ve added an audio test loop to check the selected audio input and output devices.

    On the guest side, it’s now possible to choose and test audio input and output devices before starting the session.

    SLP  Release: SessionLinkPRO | Conferencing

    We are happy to announce the commercial release of SessionLinkPRO | Conferencing. The beta test phase will end on 1st of May 2017, after an extensive testing period. Regular SessionLinkPRO | Conferencing subscriptions will then be available through our online subscription system.

    Prices and subscription periods will be equal to SessionLinkPRO | Recording:

    • 1 month: 20EUR
    • 6 months: 110EUR
    • 12 months: 200EUR
    All prices excl. VAT

    You can add a SessionLinkPRO | Conferencing subscription to an existing account or create an independent account.
