Re: bit rate and sample rate
That's a question you are best off answering for yourself by testing against the highest quality you can make to see where you can first hear a difference. If you just want to know because of a theoretical interest, pick a lossless format and forget the question. - Original Message - From: Joe n3...@hotmail.com To: pc-audio@pc-audio.org Sent: Sunday, April 25, 2010 3:59 PM Subject: bit rate and sample rate Here's an interesting question.

Re: bit rate and sample rate
Gary, I also feel that this may be an arbitrary standard. I may have been one of these who asked the question, based on comments I've heard. Of course, many say that wav is the best, but when I listen to music, or even spoken recordings, the quality may vary from recording to recording, and maybe this is all subjective at best. This is just only my opinion. Just weighing in. - Original Message - From: Gary Petraccaro garyp...@verizon.net To: PC Audio Discussion List pc-audio@pc-audio.org Sent: Wednesday, April 28, 2010 10:26 AM Subject: Re: bit rate and sample rate I tried a book I was reading for a bookclub on the Stream, and was able to go all the way to 32-bit mono. Now, I could hear a difference between that and 128 mono, but, to my aging ears, it was slight. I figure that the commercial spoken recordings issued as mp3s are at 128 and keep recordings I want to keep at that standard, but it's strictly arbitrary. - Original Message - From: Kevin Minor kmi...@windstream.net To: 'PC Audio Discussion List' pc-audio@pc-audio.org Sent: Sunday, April 25, 2010 5:31 PM Subject: RE: bit rate and sample rate Hi. Some out there will disagree with me, but that's all right. I think that for recording just speech, CD quality is overkill. Personally I would use 64 KBPS with 44.1 Khz sampling, in mono. I don't think you'd notice much of an improvement with higher bit rates, and in fact you might be able to go even lower, to 32 kbps, but you might notice some artifacts creep into the picture. As I said, this is for just speech recording. Music is a completely different animal. I personally use 128 kbps mp3 files at 44k sampling. I know it's not CD quality, but I personally like my files at a constant value, and this sounds good enough for me. Have a good day, and don't work too hard.

Re: bit rate and sample rate
The sampling rate doesn't make a difference in the size of the file, so there shouldn't be any consideration to go below 44. I've seen a lot of files encoded at 22 because the person thought it would halve the file size, but that's only an old wives tale. Try it yourself and see if it makes any difference in the size of the file. Encode the same thing at the same bit rate but at 22 and at 44 sampling rates and take a look at the file sizes. As for bit rate, whatever sounds good to your ears. I myself prefer at least 64 for mono recordings because once you start going below that, the digital artifacts start to creep in. This translates to at least 128 for stereo recordings. Some people are ok with the lower sampling rates and lower bit rates, while others can't stand to even listen to MP3 files at all, no matter what the bit rate or sampling rate. It's a very personal thing, so whatever sounds good to your ears is your answer. Laz Joe wrote: Here's an interesting question.

bit rate and sample rate
Hi. Thanks fore all the suggestions. I've experimented with a lot of combinations over the years, and you can hear the difference. I guess what I'm asking, is how low can you get away with and still have acceptable voice quality. I guess that's an impossible question to answer since not everyone's hearing is the same. A golden eared audio file will hear things someone else won't even notice. If you want to try an interesting experiment and you have goldwave and good headphones with a flat response from 20 to 20 kHz, try testing your hearing to see just how far up the spectrum you can hear a sine wave. select a kHz tone and turn the volume up just until you barely hear it. Never never go any louder than that as you increase frequency. if you don't hear a tone after lets say 16 kHz, it doesn't necessarily mean its not there, it just means your hearing probably rolls off at that frequency. Again. Don't turn up the volume since you don't want to damage your hearing. Keep it just at the point you can hear a 3 kHz sign wave. I pick that frequency because most peoples hearing is OK there, so what you perceive to be a low volume level at that frequency is probably accurate. This test is far from precise but it gives a good idea of someone's hearing range. You may not hear as high as you think you can. Anyway, thanks for all the answers. I'll continue to experiment. The recordings I'm making are just voice recordings of tutorials on how to use an amateur radio from a blind perspective that I'm putting on line. I'm also voice tagging names of albums on my thumb drive for my NLS player to be put in audio+podcasts. Thanks again. Joe.

RE: bit rate and sample rate
Yes, and I have a degree in radio television film and 192 is the correct rate for a cd. If you want to save hard drive space, you can go lower, but one can hear the difference.

Hi, for speech I would suggest 44.1 and 64 kbps. If it is a performance, sound seeing tour, or historical event I would consider either 96 or 128 for speech only.

RE: bit rate and sample rate
Hi. Some out there will disagree with me, but that's all right. I think that for recording just speech, CD quality is overkill. Personally I would use 64 KBPS with 44.1 Khz sampling, in mono. I don't think you'd notice much of an improvement with higher bit rates, and in fact you might be able to go even lower, to 32 kbps, but you might notice some artifacts creep into the picture. As I said, this is for just speech recording. Music is a completely different animal. I personally use 128 kbps mp3 files at 44k sampling. I know it's not CD quality, but I personally like my files at a constant value, and this sounds good enough for me. Have a good day, and don't work too hard.

Re: bit rate and sample rate
That's nice, but it still does not change the fact that a 128k mp3 is not cd quality. Now, for most people, 128k is perfectly fine granted, but that doesn't change the facts.

Re: bit rate and sample rate
corective is subjective. There are people who can hear the difference between 320k mp3 and flac. I can not, but they can. If you're ripping a cd, and want a perfect archive without the size of wav files, go flac. If you don't care about quality loss, then pick which flavor of mp3 encoding sounds best to you, and use it. If 128k is good enough for you, go for it. We have newer and tighter methods of encoding, but mp3 is still bmoc.

Re: bit rate and sample rate
One thing I'll add to this. if it's speach, go 64k mono, not stereo. when you take a file, and make it stereo, you have to put twice as much data into the same size file, guess what gets crunched? that's right, quality. for a drastic sample of this effect, ri9p a file at 24k mono, and then at 24k stereo.

Re: bit rate and sample rate
For audio books on CD I obtain from the public library and rip to listen on my MP3 player, I use a 44.100 sampling rate and 96k bitrate. I have found that I lose some of the emotion and distinctness of the reader at 64k. At that lower bitrate, the recording sounds flat. Broadcast radio standards do call for 128k bit rates. For personal listening of voice recordings, 96k is a good compromise for me between broadcast quality and the 64k used in many online archives. I’m especially keen to the trade offs as I am still using an original Bookport with a 512 megabyte card.

I've experimented with a lot of different bit rates and sample rates doing voice recordings but still don't know what combination of the two give good enough quality for speech. I know you need higher rates for music, at least 128KBPS. I'm only talking about voice recordings using a mic at this point. What combination of bit and sample rate will take the least space and give me fair quality speech audio. What should be higher. The bit rate, or the sample rate. I'm talking about MP 3 files. I'd like to get a better understanding of this. Thanks in advance. Joe.
