Any Sound Device From Daily Divices

Is there any device that can store all my daily mechanical energy of walking, talking etc. into some device?

You are expending just enough chemical energy to produce mechanical energy of walking, running, exercising and every other mechanical move that you do. There can be devices that can store it. The catch is you have to exert more than what you are doing to produce that extra energy that you can store thus.Talking is the only exception where the energy is converted to change of kinetic energy of air (the medium) which travels in all directions and dissipated. This energy can be captured.

Name one device in which sound energy is produced from electrical energy?

I’ll go for a list:Loudspeakers: those are designed to transform electrical signals into sound, hence they’re very efficient.Earphones, the modern ones, likewise efficient.Electric motors, designed to produce mechanical energy, they generate noise as by product. Annoying sound, also mechanical energy, but it sounds.Fans. Have you ever heard them while they’re blowing?Transformers. They do make noise, no matter if electric transformers or TV “transformers”Power lines: they’re always buzzing due to the corona effect.Ink jet printer heads: they kind a sing while printing. Don’t confuse the printer head noise with the steppers noise, which are a lot louder.Toasters: high current on their resistors make them buzz a little.Piezoelectric cristals: they’re used in high frequency tweeters, printer heads, ultrasound transducers, motors, etc.Electric arc: if well driven, they can play music.Your stereo.BestCD

What are examples of devices that use direct current?

The list seems almost endless, for the answer spans from flashlights, to electric automobiles whose energy is stored in batteries, computers to model airplanes and drones, LED illumination and cell phones, digital camera’s, TV Remotes, and virtually anything that is powered by batteries, Your electric toothbrush, or your watch and often the wall clock, or and on, and on, and on. Sometimes, Solar cells(DC) generating DC that is converted into AC for appliance , fe.g. furnace fans, laundry dryers, air conditioners, and refrigerators and often, AC is converted then into DC for small power devices like CD players, and chargers for recharging battery DC devices. We’re all surrounded by devices powered by DC

Should I buy an audio interface or get my sound card on my computer replaced?

I love reading the comments below because I know exactly what you're asking. I'm not sure if this question is still an issue for you, but for you and anyone else reading1) When people talking about recording say "Audio Interface" they're talking about external hardware that mostly functions as a recording device such as Avid's MBox or Steinburgs UR series.2) When anyone mentions a "sound card" they're referring to the PC's sound... card. I'm not sure why some of the other posts were so condescending over a question that should have been obvious to anyone with that much experience.First off... you don't mention your setup or what "Youtube covers" is, so I'll make this easy...If you're going to use actual instruments, get an external "audio interface". I, personally, use the Steinberg UR44 (which has plenty of features for recording) and I love it. It's headphone jacks also pass enough power that you won't need an extra OP amp to power them (I can only confirm the UR44 has this, though I'm sure many of it's competitors also do, double check just to be sure). Steinberg also has really great customer service and they'll answer any question you have no matter how stupid (^_^). For your price range, the smaller models should be sufficient, and they run about $200.I assume you're going to be playing an instrument during the recording session, but, if not... then get a sound card. I recommend Asus sound cards or Creative Labs, but mostly Asus (Creative Labs if you also do a lot of online gaming).As far as hardware/software compatibility... Avid, Focusrite, and Presonus are the most commonly found, but Steinberg products can outshine them... if you're willing to use all Steinberg hardware/software. Their products really shine when used together (not in the same way other products do, mind you), but that quality drops quickly when mixing and matching, so there's plenty to think about. I've always liked Cubase and I didn't even know the UR44 was Steinberg until I bought it, but I loved them. Your results are almost guaranteed to vary, so you'll have to think it over. Also, if you're using Midi devices, you'll need an audio interface that has a compatible jack for it, so be sure the product you're buying suits all your needs. Or, you could post what you have and what you want to do and I could narrow the list down. If I missed anything or if you have any other questions, ask away.Teaching or learning... I do love music.
