![]() ![]() In other words, if you are having difficulties to pronounce a word in a foreign language, you can take the help of Google Translate to get the job done. For the users’ benefit, it lets you listen to converted text on the website. Google Translate is a top-notch tool to convert text from one language to another. Also, you can download the source text as well as converted text as MP3 audio by following this step by step guide. No matter whether you are using Google Chrome, Mozilla Firefox, or Microsoft Edge browser, you can use the Google text to speech app online to extract audio. You can convert text to speech online by using Google Translate as a TTS online. If you are thinking like how do I download audio from Google Translate or convert Google Translate to MP3, you are on the right page. Other than that, to actually capture and/or reproduce sound in real low bit-depth, I guess you would have to use a microprocessor platform, like the Arduino or the TIva LaunchPad, and do you own programming.You could even create and directly program your own "low-bit" compositions.īTW, in this regard it may be interesting to check the work of composer Tristan Perich, who created and distributed 1 bit-depth music through a simple dedicated electronic device.If you want to download audio from Google Translate, you can follow this tutorial. WAV) require it, but they will sound as the lower bit-depth audio you created. Note that you will also be creating your files with higher bit-depths, as the file formats (e.g. Many decimator/bitcrusher effects (including the one in Audacity) also allow resampling and quantization by non integer proportions. Hence the more technical name "decimator" (Bitcrusher is just a another name for the same thing). low order bits from samples (to reduce bit-depth by powers of 2),.The basic technique to do that is just to discard either Result using the Nyquist procedural language]. Plugins pack LADSPA [thanks to for noticing that andĬheck in a comment below his alternative approach to achieve the same Install package, but it's part of the Audicity "sponsored" additional Note: actually the Decimator filter is not part of the Audacity So in practical terms Todd Wilcox's suggestion of "lo-fiing" your audio by software is a good one, and BTW, there is a filter in Audacity to do just that: Effect/Decimator. In principle it would not be hard in the software driver to quantize the samples to lower bit rates, but again, why would a manufacturer bother to overload their sw with features that almost nobody would use? Audio interfaces or other capturing devices have their ADCs (Analog do Digital converters) based on integrated chips optimized for the features that are most requested commercially. Lower bit depths are not easily available simply because they are not looked for commercially, not because of some intrinsic technical difficulty. However, I cannot seem to find which programs or techniques are used to record at low bit-depth, or if they record at 16-bit and then lower the bit depth of the already recorded signal (I believe this is called "bit crushing" technique?). Sampling Frequency and Bit Resolution for Speech Signal Processing. If not, can you explain why this seems not easy to do with default/most common linux programs (Audacity, sox, arecord, etc)?ĮDIT: I've found this very interesting article about speech processing in different sample rates and bit depths, which is precissely the field I'm investigating also: So, my question is, do you know of any program or command that would allow me to record at lower-than-8-bit depths? (Preferably linux). ![]() But for learning purposes and from a theoretical point of view, it should be possible to record an audio signal at arbitraty low bit depths such as 2-bit, 4-bit, etc.įor example, in the Audacity Wiki ( ), it is mentioned that a cassette is equivalent to a 6-bit depth, and that an Edison Cylinder home recording is as low a 2-bit depth in resolution. I'm aware that this is probably impractical and also that 8-bit is a byte and probably that's the reason why programs don't usually go lower than this, because of integer data types representation. Also the bit depth is easy, but I cannot find a program or command that would allow me to record at lower bit depths than 8-bit. The sample rate part is rather easy, many programs like Audacity in linux give this possibility. First of all, sorry if this is not the right stackexchange site to ask this, but here it goes.įor research and learning purposes I want to record wav files at different sample rates and bit depths and compare the recordings, listen to their differences, etc. ![]()
