  • Audacity - Latency

    I am having a slight problem recording with Audacity and I THINK it may be a latency problem. If so I was wondering if anybody had any advice.

    The problem occurs as I am recording through my soundcard. I will be playing some loops and doing a live recording through the soundcard using Audacity. I use ALSA as the Audio host and use pulse as the Input device.

    It records fine except for the face that thee is an occasional drop in the recording. The drop is very short and on playback it sounds like a click.

    This could be an issue with the operating system (I use Linux Mint) but I doubt it
    This could be a RAM issue - I only have 4 gigs of RAM on this old netbook. I am inclined to doubt this as this is the only occasion in which this problem occurs
    That leaves latency issues with Audacity. I know I can later the latency settings in preferences but have not had a lot of success so far.

    Anyone else have any suggestions?

    4GB is a little on the low side, but would guess the culprit might be the soundcard.

    Unless you are using one designed with recording in mind, often they are not fast or robust enough to give you a decent round-trip time while recording or performing.

    But pops and clicks are usually buffer underrun problems; Your CPU will contribute to drops and pops if it is older tech (single or dual core, lower clock speed).

      4GB isn't necessarily low in terms of available memory. The Linux VM system is quite robust. I have heard of latency issues with Audacity and pulse, but stopped using Linux for audio about 6 years ago, so I don't have any up-to-date knowledge of the subject.

      Did you see this:-

          Does anyone have any other methods of recording through the soundcard other than using Audacity?

            Audacity is fine, I used it for years, but it's really basic. I stepped up to Reaper and love it. Far more capability, not very expensive, and much easier work flow....

              I had this issue years ago. It was due to the lack of processing capacity of the laptop I was using - Celeron processor, 4GB RAM. A better laptop solved the problem. (i5 processor, 8GB RAM)

                Cut out pulseaudio, and use JACK for low latency audio on Linux.

                (I used to be a developer for Gentoo Linux.)
