Amplify in Audacity
I recently dowloaded some digital
music files from Amazon, and loaded them into Audacity sheerly for the sake of futzing around with them. As they were recent tunes, they exhibited the typical maxed out appearance in the workspace. But what really shocked me is what happened when I selected a song and the amplify tool: The nominal amount of available amplification was -1.8dB for one song - MINUS that is! How could that be, in digital where 0dBfs is the absolute ceiling? So sure enough, I applied the -1.8dB of amplification, and ended up with a slightly raggedy looking envelope instead of one that *appeared* brick-walled. I thought these digital files were peak-limited in mastering. Or am I missing something? |

In fact, over the years their existence has been somewhat swept under the rug here on Usenet and on pro audio forums I frequent. When exporting a lossless project to a lossy codec, I either peak limit half to one dB below full scale, or, amplify project so that highest peaks are no closer than that amount to full scale. Guess the engineers who mastered those Amazon files didn't think ISPs exist either! |

Guess the engineers who mastered those Amazon files didn't think ISPs exist either! So, I have an graphic equalizer on WinAmp, think +/- 12 DB. Can I move it any and destroy peaks? You know, saturation? I'm no advocate of brick-walled sound, but a peak is a peak, it's not like RMS, so you lose a few peaks, no one will ever notice. Jack |

You guys are a bunch of WIMPs,
scared of a garbage-spewing BOT. |

I have a Dusty Springfield hit tune that has a distinct DC offset (I thought), I could not correct. Audacity shows a peak about 17kHz!! I can truncate with Goldwave, but it really changes the waveform!! I GUESS I'm the only one who notices these oddities, with my non-fancy audio software!! Jack |

I know Scott and I disagree, but this Son Of A Preacher Man song, music intro is fine, but I'm guessing where the vocals were mixed/added, then you see the 16kHz VU bar remain constant/static. Why I preach about varying DC offset, even though this doesn't appear to be the case here. What caused it is beyond me. Jack |

Most thought good/great idea, since "mixing" is a pain, especially when you have a perfect (stereo) mix, but find output too high!! Also, when multi-tracks surfaced, many claimed you need "newer" Audacity version, that was a crock. Shows me how little others know. Actually, I'm impressed with recent Sgt. Pepper remixes (comments of others), some are finally catching on. Giles Martin needs training before using DAW. Jack |
