Sådana här ekon brukar vara att man har lyssning både direkt, genom ljudkortet och genom inspelningsprogrammet. Stäng av lyssningen genom FL Studio. Manualen säger följande:
Monitoring: By default, incoming audio from the armed mixer track is routed to the Master mixer track and the delay between making the sound and hearing it in FL Studio will be equal to the latency settings of your soundcard. If the latency is too large, your monitored sound will echo against the live source, causing problems for anyone trying to perform along with the project (e.g. vocalists). If you are troubled by latency echo you can stop the incoming audio passing out of FL Studio by de-selecting the 'Send to master' knob in the track you are recording into. However, since you will no longer be able to monitor your input signal, try lowering the latency settings to see whether the latency echo can be eliminated, or more preferably, use your soundcard to perform 'direct monitoring'. Direct monitoring works by routing a copy of any incoming audio directly into the soundcard output without passing through your computer and therefore without producing latency.
