Members techristian Posted December 14, 2016 Members Share Posted December 14, 2016 "File compression format found to alter timbre of music causing loss of some emotional context" This isn't hard to see when you realize that compression will make the louder parts quieter and the softer parts louder, so you won't jump out of your seats when the 1812 overture canons go off. https://techxplore.com/news/2016-12-...usic-loss.html Link to comment Share on other sites More sharing options...
Members 1001gear Posted December 14, 2016 Members Share Posted December 14, 2016 Same can be said of simply recording something. Link to comment Share on other sites More sharing options...
Members UstadKhanAli Posted December 14, 2016 Members Share Posted December 14, 2016 Now have them do another study comparing the emotional response to 8-track tapes. That should be a far more dramatic emotional drop-off! Link to comment Share on other sites More sharing options...
Members Jasaoke Posted December 15, 2016 Members Share Posted December 15, 2016 I can't count the number of great songs that I hated because I heard them on the radio. Compression kills. Link to comment Share on other sites More sharing options...
Members Anderton Posted December 19, 2016 Members Share Posted December 19, 2016 The graph shows 112, 56, and 32 kbps. Well of course those sounds suck! The conclusion I would draw isn't that MP3 per se is the problem, low bit rates are. Hell, if you listen to a WAV or AIFF 24-bit file with a 16 or 32 kHz sample rate, it's going to suck too. I have the Sonnox Pro Codec that lets you hear what's removed when converting uncompressed to compressed formats. Once you get above 256 kbps, it's mostly scratchy, treble sounds, and not much of them. I'm not trying to defend MP3...I'm trying to say I think the study is flawed, to say the least. How much is lost with vinyl when you boost and cut by 20dB going in and coming out? Here are the results of my survey that includes a sample of one person (me): Live music sounds more lifelike than recorded music. Can I get a big grant now and be considered a Famous Researcher?

Members AlamoJoe Posted December 19, 2016 Members Share Posted December 19, 2016 I heard Cream play "Crossroads" live in concert...On vinyl, on 8 track, on cassette, on cd, on MP3....It rocks in any format or form. Jus' sayin'.... Take a breath folks.... Link to comment Share on other sites More sharing options...
Members gismo recording Posted December 21, 2016 Members Share Posted December 21, 2016 Your second sentence is talking about a different kind of compression. mp3 compresses a wav file to make it smaller but still sound the same (almost. Some of the higher frequencies are lost, ones that no one over 50 can hear anyway.) Compressing sound to decrease the dynamic range is something totally different.

Members Notes_Norton Posted December 21, 2016 Members Share Posted December 21, 2016 Dynamic compression of any type diminishes emotional content. How much compression vs. how much degradation is the question. After all, dynamics in speaking, singing, and playing are all emotional conveyances. When recording backing tracks for my duo, I do not compress at all. However, as a compromise, I may use a peak limiter for a stray wild peak or two and then bring the track level up a bit. When doing studio work, I let the engineer worry about that. I'm just sax for hire so I prepare and then play my best to support whatever I'm hired to play on. But there is more than one correct way to make music. Notes Link to comment Share on other sites More sharing options...

But it seems the topic is going in the direction of dynamic range compression, which is not what the article is about. Link to comment Share on other sites More sharing options...
