If you are hearing echo of yourself, it means the other end is using a speaker/microphone set that doesn't have echo cancellation built-in the hardware or software driver. There are a couple of ways to avoid this:
1) Use a headset instead of speakers
2) Use a microphone that has Acoustic Echo Cancellation (AEC)
The following devices support AEC, and had been confirmed to work with ReelPortal:
- Asus EEE 1000HE netbook (using RealTek HD Audio driver). Fortunately, many netbooks have this driver as well, or something else that's equivalent.
- LG MSB-100 Bluetooth Speakerphone (~$20 on ebay). Other bluetooth speakerphones should also work (check Amazon.com for Motorola EQ5, EQ7).
- Logitech EasyCall desktop speakerphone (must use with Logitech driver).
- Logitech QuickCam Deluxe for Notebook, using Logitech QuickCam 10.xx software (for Windows 2000). Do NOT use the latest Logitech driver/software (for XP, Win 7), as they crippled it so that AEC only works with their Vid software. Update: Acoustic echo cancellation ("AEC") is no longer available with versions 11.7 and higher of the Logitech® QuickCam® software. AEC is available from most leading video-calling applications (link). In other words, new Logitech webcams do not have AEC in the drivers!
- Logitech QuickCall Speakerphone (available on ebay for ~15 USD) is another great product with AEC.
NOTE: Logitech AEC may introduce some delay in the audio playback on slow systems.
Please report other devices with AEC confirmed working with ReelPortal. Thank you.
