Audacity Forum

my Win10 computer Is that a laptop or a full-size computer? For a full size computer you must use the "line in" and not the "mic" input. The output from a cassette player is around 1000 x higher than a microphone signal, and could damage a mic input. On laptops, there is usually...

Unfortunately, moderators still are suspecting me of something hideous and disabled BBCode and all stuff in my messages... Please understand that keeping this forum free of spam, {word rejected}, trolls and flame wars ... is a lot of work. The small team of moderators and forum friends that keep th...

Why should I edit without “bit-perfect” in mind? "Bit perfect" is one of those phrases that is easy to grasp, but not really very meaningful. 32-bit -> 8-bit is obviously not bit perfect, right? but 8-bit -> 32-bit -> 8-bit may be lossless. 24-bit -> 64-bit -> 24-bit -> laptop / iPod / ot...

Why do you need "bit perfect"?
Where do the original "bits" come from?

I would prefer the best quality over browser support-- while keeping the file sizes within a reasonable size. It depends what you mean by "reasonable size", and how long the audio is. For short files, 16-bit 44100 Hz WAV will give CD quality, which is better than any MP3 or OGG. If that's...

MP3 is still the best supported audio format for web browsers.

Here is a very small 32-bit float number as a decimal to 50 decimal places:
0.00000002683188249363865907071158289909362792968750

You might want to read a bit about IEEE 754 standard to get an appreciation of why this is complicated:

You could use the envelope tool *http://manual.audacityteam.org/man/envelope_tool.html) to control how much of each track:

Plug your mic and headphones into the focusrite. Don't launch Audacity, leave it closed. Ensure that the "direct monitor" switch is on. Can you hear the mic through the headphones with no delay?

Note that the more decimal digits, the bigger the file size. Each digit is 1 byte, so 16 decimal places, plus a leading "0." or "-0." and a new line character, is 19 or 20 bytes per sample, so 1million samples will create a file that is close to 20 MB.
