Your best bet is to see what formats youtube-dl returns by running at a command-line, youtube-dl -F URL which will produce output looking like this format code extension resolution note 249 webm audio only DASH audio 53k , opus @ 50k (48000Hz), 4.25MiB 250 webm audio only DASH audio 72k , opus @ 70k (48000Hz), 5.53MiB ...

This guide worked 100% for me - it takes you through each step. Afterwards, the m4a file plays! Note: this is completely free. http://sysfrontier.com/en/2014/12/31/hello-world/ Also pasting instructions in case the link goes down in future: How to fix corrupted voice memo (m4a) files. Do you have broken voice memo files? You can fix those files by ...

Whichever app you use, you'll want to line them up and then invert the phase on one of them. Depending on how identical, and how they were made, it might easy to line them up and get an accurate result, otherwise you'll have to spend some time trying to line it up as best you can by zooming in on the samples. The idea being that if you have two things that ...

The basic idea The characteristic "wobble" bass popular in mid-late 2000s dubstep is frequently (but not always) created by sweeping a lowpass filter over a harmonically-rich sound of some kind, usually some oscillators. The filter cuts out the higher harmonics, creating an effect similar to closing your lips while saying "ahhhhh. By moving the filter ...

The purpose of a direct box is simply to take a quarter inch guitar line signal and convert it to a balanced signal that won't degrade over the longer run to the sound system. A DI doesn't do anything that can't be done with a decent recording interface since you aren't going a long distance with the signal. You are best off to get an audio interface that ...

Audacity is a great tool for this kind of work. You might be able to make a slightly better sound using a sampler that can crossfade across different sounds for different pitches, but I'm not sure if the result would be worth the extra effort. It sounds to me like the problem with your "current best" is that you either aren't looking for zero crossings when ...

You can use MIDI CC 5 - Controls portamento rate to slide between 2 notes played subsequently. MIDI CC 65 - Portamento On/Off switch | 0 to 63 = Off, 64 to 127 = On MIDI CC 84 - Controls the amount of Portamento.

Once a signal is digitized it is treated as a number (as you quite rightly point out) and for 16bits the range of numbers are -32768 to +32767. The numbers are created by an analogue to digital converter. The analogue to digital converter (ADC) will have a maximum input range from -X volts to +X volts (i.e. real signals that you could measure inside your ...

There are three parameters of this filter that are described in the phrase "100 Hz 12 dB per octave low pass filter". I'll cover them in reverse order. Low pass filter - This means the filter does not change lower frequencies ("passes" those frequencies through) and blocks higher frequencies. Sometimes these filters are called "high cut filters", but that ...

That's still an EQ, you just cut the bands to -infinity. More specifically, you would want to use a shelf EQ if you have it. Also sometimes called high pass and low pass filters.

The only "natural" (i.e. "using only the data in the sample") way to change the pitch of a recorded sample is to change the speed of its playback. So a sample that sounds an octave lower should take twice as long to play back. But you have a tool that somehow manages to play that sample back octave lower, while somehow keeping the playback time the same. ...

Audio CDs are encoded with 16-bit values. Higher bitrates are generally used for editing, not for playback. You can write 24-bit WAV files to an optical disc, of course, but it will not be a standards complying audio CD.

I strongly disagree with a lot of Dave's recommendations, based on my experience recording vehicle sounds for racing games, advertisement and sound engineering: an engine under load doesn't sound like an engine revving while standing still at all. "patching in after the fact" will be loads more work than recording audio and video at the same time. Expect ...

Does more impedance mean less volume ? As to impedance, take a look at Bill Griddle's answer: https://video.stackexchange.com/questions/650/what-is-the-effect-of-impedance-on-headphone-sound-quality In essence: yes, higher impedance = lower volume. But higher volume is not necessarily better quality. Most professional headphones has a high impedance. Are ...

SoundIt does just that. And it lets you stream the sound output of your PC to any web browser so you can stream to any phone or even another PC.

This is a matter of taste more than a technical issue, so I'll be using terms like "groove" and "feel" rather than more quantifiable criteria. It comes down to making it seem natural instead of jarring. Since you mention club DJs, I presume you mean "in front of dancers," and the human body is going to move differently at 90bpm than it is at 130. A simple ...

Go to Devices/Device Setup then under VST Audio System on the right side of the window Tick the option underneath ASIO Driver that says release driver when app is in background... ;-p that worked for me.

A good digital signal should either get there or not. Minor differences in cable quality are not going to have any impact at all other than latency. Latency is simply the delay in how long it takes to get to point a to point b and won't impact the sound quality significantly. USB is a digital signal, so a "premium" USB cable is a load of crap. There is ...

What you need is a sequencer that can also handle audio data, or an audio suite that also handles sequencing. Collectively, these programs are known as Digital Audio Workstations, commonly abbreviated DAWs. While the term "DAW" technically refers only to audio editing (waveforms), it's very common for a DAW to also support MIDI sequencing, or to be more of a ...

Note that SyxEx data is, by its very nature, vendor specific. Supporting detailed SysEx editing would require custom work for each MIDI synth ever made. EMagic's Sounddriver did this, but was discontinued shortly after Apple bought EMagic. You can accomplish a lot of MIDI and SysEx manipulation with Logic's environment, though it is awkward, poorly ...

Your best bet will be to run your source material through a bitcrusher and a sample-rate reducer. However, that will just make it sound like the kind of low-quality samples that could be played back on old machines. Actual chiptune music tends to involve very careful use of low-resolution waveforms and FM synthesis.

I think the most straight forward solution would be using a DI unit. Once you connect it to your source(PC), you will have a balanced signal which you can safely carry on a balanced cable for 100ft (or even more).

Mixing audio in a computer is very analogous to how sound mixes in the real world. In the real world, sound is simply pressure waves that cause vibrations in our eardrum that get converted to what we hear by our brain. In the computer, that level of pressure of the wave is represented as a series of samples that describe how strong the pressure wave was. ...
