Re: Removing blank audio in front of songs

I got the audio from youtube, which only allows MP3 files. Youtube offers other formats besides MP3 which may be more suitable, such as Opus. Opus is a more modern codec (and is currently one of the best available) that doesn't have the sort of issues that MP3 does. (Of course, if the video was ori...

Re: Microhpone advice needed: Blue/Yeti vs Rode NT-USB

But there's another layer as well. I know you don't do this, but nothing drives me to homicidal fury faster than watching a "How To" video that makes a mistake and then makes me sit through them correcting the mistake. Even with ElectroBOOM's "How To" videos ? He has a knack for making mistakes. :l...

Try around 14247.50 kHz, USB (Upper Side Band).
Not with the audio sample posted. There's nothing above 8 kHz.
Right. Sorry, I should have clarified that my comment was sort of in response to Koz's as an example of tuning too high or too low with SSB.

Re: Demodulating Single-Side-Band

Sometimes I find learning easiest with a real-world example. Northern Utah WebSDR lets you listen to actual radio transmissions in SSB (as well as other modes). Move the yellow "bracket" left and right and hear what it sounds like. Try around 14247.50 kHz, USB (Upper Side Band). (The 20m band seems ...

Re: mhz x audacity

It seemed to work and I saved it as a WAV file. The sample rate field in the WAV file header is 4 bytes, so that limits you to about 4MHz sample rate. I think the maximum sample rate that WAV supports is about 4GHz (with 8-bit samples and 1 channel, because the ByteRate is computed from the sample ...

Re: Everyone laughs at me when I say I record with Audacity

Of course, Audacity supports (and uses by defaults) Shaped dither (to be pedantic ;)) By default, Audacity does not use dither when mixing, because (by default) it's all 32-bit float. Dither is only required on export if the export format has a lower bit depth. Touche. :D Yes, I meant when exportin...

Re: Everyone laughs at me when I say I record with Audacity

* Mixing is just summation so again, your choice of software doesn't affect quality. To be pedantic, software can affect quality, even when "just" mixing, if there's any gain changes on any of the tracks because it can introduce quantization noise if it's done naively. Of course, Audacity supports ...

Re: Digitizing vinyl

-Is MP3Tag only applicable to my tracks once I have exported them to my library (which I do in WAV format, which it supports... supposedly)? -Am I better off using MP3Tag to convert my projects to MP3 format (necessary if I want to play them in the car), rather than converting/exporting them direct...

The loosely accurate % rate from this attempt was 8.867% change.
With that high of a speed change, it sounds like one of the recordings (the longer one) was actually taken at 48000 Hz instead of 44100. Speeding that up to match 44100 would be about an 8.844% change.

Re: 2 Remote Podcast Recordings, 2 different final length

Just to be clear, chances are good you're not both running at 44100.00. One of you may be running at 44100.01, for example. You're experiencing that tiny difference in sampling rates. In film terms, one of your cameras is slightly under or over-cranked. Effect > Change Speed is the least damaging o...
