![]() I won’t change the default sample format. I have provided here on the crackling ONLY happening while recording through the line input of my external USB soundcard (and NOT while recording through the laptop’s built-in microphone jack) help any of you to narrow down the cause (and possible solution) of this crackling problem? (1) Should I change Audacity’s default sample format from 32 to 16, so that it is the same as that of my external USB soundcard? Audacity’s default sample format is set at 32-bit float, whereas my external USB soundcard is set for 16 bit. However, the sample format is different for each. by typing in mmsys.cpl, etc), the sampling rates on both Audacity and the soundcard (for line-in recording-which is how I’ve been getting the crackling) is 44100 Hz. Regarding jademan’s suggestion that I check the sampling rates of both Audacity and my external USB soundcard via windows (i.e. So, the crackling problem seems to be linked to my use of the external USB soundcard for recording purposes (but, when I just play music from Youtube, Windows Media Player, etc, there is no crackling, unless, of course, I am playing back something that I recorded through the external USB soundcard). In general, the signal isn’t quite as good as that coming through the external USB soundcard, but it is still pretty good. When I first got Audacity months ago, I had no external USB soundcard, so, temporarily, I just used this mic jack. Firstly, I am not getting the crackling problem when I record (my mixer, guitars, mics, etc) through my laptop’s built-in microphone jack. I’ve continued to try the different things that have been suggested, and, although I haven’t finished with this yet, I have made some more useful observations regarding the problem. And, if I change the buffer length, should I first try going up from, let’s say, 100 ms to 110 ms, or move it up more incrementally, such as 101 ms or 102 ms? ![]() I will try doing that tomorrow when I have more time to experiment. So I’m a little confused about that.Īlso, your advice to minimize my use of apps etc. And, after reading your response to my original post, I checked my recording preferences settings to see if the dropouts detection setting was on, and it was. If this crackling problem is indicative of “dropouts”, wouldn’t I be getting the dropout window popping up to inform me of it? I tried recording some cassette tapes today to see if I could identify the source of the crackling, and I never got any dropout window or alert. ![]() I don’t believe it has come on since then, but I have had the crackling problem getting worse lately. I did have a problem one time in the last couple of months or so when parts of a recording/tracks were apparently lost, and I recall getting a special window/alert pop up (which I don’t think I ever received prior to that) saying that some of the audio was lost, etc. If anyone can help me to solve this problem, I would be very grateful. ![]() I can’t figure this out, and it is preventing me from doing all my audio work. However, when I play the cassettes through my mixer and monitor it directly from the mixer itself, or sing through a mic into the mixer and monitor it through the mixer, or play a guitar through the mixer and monitor it directly through the mixer, there is essentially no problem. Whether I try to record a mic or guitar from my mixer to the external USB soundcard/laptop or record a cassette tape from my Sony dual cassette player/recorder to the soundcard/laptop, I am running into this same crackling problem. One strange thing I just noticed today regarding the crackling sound is that it happens at very regular intervals-they tend to occur every 2 minutes and 20-30 seconds! In between these times, the recording is generally very clear and basically sounds good. So, I felt hopeful that by turning off the Software Playthrough function, my problem would disappear. Generally, for months I have not had it on, and, instead, monitored myself though my mixer while recording. The advice was to turn off the Software Playthrough function. I just read a post from 2014 about a similar crackling problem, and Steve’s advice to the gentleman who asked for help seemed to resolve the issue. I don’t believe I have had anything like the consistent crackling problem I am now experiencing. Before I got the soundcard, I went from my mixer to the built-in microphone input on my laptop for recording purposes. I use a StarTech external USB soundcard, and, aside from the crackles, the sound is great. Over the months that I have had Audacity I have had minor crackles or individual cracks, but in the last month or two the problem has gotten far worse. I have an HP Elitebook laptop and Windows 10, and am using Audacity 2.4.2. I am getting a bad crackling sound when I am recording and hear it upon playback at exactly the same points.
