I wish to play a short sound in an app (60 Milliseconds is ideal), however I'm noticing glitches in the sound on the current clip I have made.

I'm wondering if these glitches have to do with any ambient noise and improper audio recording (by me). I.E.: audio with reverb is longer than the audio length (after cut).

So my question, Is it possible to record such a short sound and (after noise reduction) won't sound like a static glitchy mess?

I have a Zoom H4N, and am using a sample rate of 48000 Hz. I suppose if I lower my mic gain, I can try to eliminate some noise off the bat. Otherwise I'm not used to having to be this specific about recording audio, so any help is appreciated.

Just for a background on the sound I'm trying to record: Try picturing a short synthesized beep, except created through percussive means (ex: a clap, or a knock on wood, etc.). The more I think about it, I feel like the reverb of the short sound in the room might make this difficult.

Alternatively, would a MIDI sound be a better choice?

  Hi Matthew and Welcome. A sample of the sound would help provide better answers, as we'd know what kind of distortion or artifacts you're referring to. Does it only sound distorted when played back through the phone's speaker/s?

You can use any sound you like and at the length you want, if you use an simple audio editor like Audacity, or a more advanced solution that can offer MIDI/synths, and additional tracks like Pro Tools.

I would first source the sounds either by recording them or using an instrument or synth that you can record into a digital audio workstation, then edit and fade them to the length that is most compatible.

When exporting the sounds, ensure that it is also compatible with the app or mobile OS by also matching the correct sample rate and Bit depth. You might benefit by converting it to MP3 to save disk space (Audacity or iTunes can do this).

You're probably experiencing the joys of a non-zero crossing at the edit points. Sure, you can record a sound and then shorten it in a DAW, as Joel has mentioned, but you do need to make sure you put a short fade in and fade out at the start and end of the sample.

If you do not, the DAC will have to deal with outputting sample values that will ensure that you have a very hard edge at the start and end of the sample which will result in a very nasty audible click at the start and end of playback.

To fix this you need to fade that sample in gradually and then fade out again. Doesn't have to be a long fade, just enough to get from a sample value of 0 to your audio level and then back again to zero once you have finished.
