Speak Freely for Windows

1. Your network connection isn't fast enough to send real-time audio with the compression modes you've chosen. Try additional compression to reduce the volume of data you're sending.

2. The compression mode you've selected (usually GSM, LPC, or LPC-10) requires more computation than your computer or the computer of the person you're talking to) can perform in real time. Choose a less efficient but faster form of compression. The performance benchmark can help determine which compression modes are within the computing power of your machine.

3. You've chosen encryption mode(s) which require more computation than your computer can do in real time. Use fewer or less computationally intense modes of encryption. DES is the slowest form of encryption, IDEA is intermediate in speed. Key file encryption requires virtually no computation. If you've selected multiple encryption modes, the computation required is the sum of each of the individual modes. The performance benchmark can help determine which compression modes are within the computing power of your machine.

4. Your machine may be sufficiently slow that the mechanism Speak Freely uses to guard against system hangs due to overload is itself creating delays which cause packets to be lost. You can disable the system hang protection with the Options / Workarounds / Network/ Disable Message Loop Insurance menu item, but it's unwise to do this before you're absolutely sure the compression and encryption modes you're using don't overload your computer.

You can experiment with various compression and encryption modes without disturbing other users by connecting to one of the Speak Freely echo servers.
