Somewhere between 32 and 96 kbps is appropriate with diminishing returns beyond 128kbps.Sample rate is the number of times per second that the sound is digitally recorded. The latter is a measure of filesize and download time and also a rough measure of quality. Estereo unido ( Joint-Stereo ) en lugar de Mono o Estereo Completo ( Full Stereo )Note that 'sample rate' or frequency, measured in kiloHertz (kHz), is not the same as 'bit rate', measured in kilobits per second (kbps). Tasa de Bit Constante ( Constant Bit Rate (CBR)( en lugar de variable (VBR) con una tasa de muestreo de 11.025, 22.05 o 44.1 kHz
Grabar Voz Full Orchestra Crescendo
If audio files report that they are much longer or shorter than they really are then VBR incompatibility is a likely cause. Constant Bit Rate mp3s can be seen therefore as wasteful as they use the same amount of bits for silence as they do for a full orchestra crescendo but are more compatible and easier to stream. You might sometimes find MP3 audio files at 16, 32 and 48 kHz but these can cause problems with Moodle and elsewhere and so ideally should be re-encoded following the instructions given below.Variable Bit Rate files are commonly used to get the best audio quality by 'saving up' bit on easily encoded sections such as silence or simple audio and then using them for difficult to encode noises such as applause, harpsichords or hi-hats. 44.1kHz is probably the most compatible and a good default choice but 22 and 11kHz are fairly standard too.
Grabar Voz Mac And PC
Don't tick "Use Variable Rate Encoding" Stereo Bit Rate: your choice. The following instructions are for iTunes which is freely and easily available for both Mac and PC.To change the settings used to create or convert audio files, open the iTunes option screen, then select:Options -> Advanced -> Importing, then select MP3 Encoder then from Settings: select Custom. The Media Filters can have issues with some mp3 audio files produced by third parties, that would play fine if downloadedIf you have audio in one of the other formats listed above but would prefer it in the widely compatible MP3 format detailed above then most can be easily be converted. consistent user experience across platforms (Mac, PC, Linux) as it plays in the browser Widest possible compatibility (both software and hardware)
After selecting the file you should find an option in the Advanced menu, called Convert Selection to MP3. Tick "Filter frequencies Below 10 Hz" (this generally doesn't have any effect but doesn't really hurt and can increase quality)If you have played the file in iTunes you should be able to find it in your library. Don't Tick "Smart Encoding Adjustments" (this doesn't have any effect unless you have left some settings at 'auto')
It is available for Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems. The information in this page maybe moved to their own pages in the future.Usando Audacity para convertir audio y grabar vozAudacity is free, open source software for recording and editing sounds. From 32 to 96 kbps is roughly the right area for recording speech.Please see the complete list under See also. You can experiment to find the right mix of size and quality appropriate for your content but anything over 128 kbps is probably a waste of time and space for anything other than recording high-quality music, as is anything higher than the bitrate you start with if converting from one format to another. If you're not going to reduce the bitrate by 50% or more you would probably be best leaving it as it is.MP3 bitrates can range from 1 to 320kbps. It is the equivalent of photocopying a photocopy and each copy introduces degradation and artifacts.
