53 Royalty-Free Audio Tracks for "Gradually"

We develop iphone app that perform musical analysis on recorded audio from the iphone. Our app implementation make use of the audio queue service to receive raw audio buffers from the audio queue callback. In the first version of our app we had the problem of too much clipping on the recording which degrade the accuracy of our analysis. We also suspected that the noise canceling algorithm in iphone 5 produce distorted sound, which is not much noticeable by human ear but distorted enough to affect our sensitive algorithm. We found that the solution to our problem is to set the audio session mode to kaudiosessionmode_measurement. This session mode is supposed to give maximum freedom for us to control the microphone input, which include turning off the automatic gain control and probably noise canceling as well. The solution works very well except that it introduce a strange waveform pattern in the beginning of all recordings in iphone 5. It is very hard to explain the waveform we get, so i made two recordings at freesound so that you can see it visually. The first recording is made in an almost quite environment, and you can see the weird spike in the beginning of the recording. The second recording (this recording) is made with constant background noise, and you can see that the actual sound wave is offset from the strange curve and gradually increase to its original volume. This waveform only happens on iphone 5 devices that we tested, and there is no problem at all for iphone 4s and older generations. We have tried various settings and the glitch is still unavoidable as long as we set the audio session mode to kaudiosessionmode_measurement. We also find similar glitch in one of our iphone 5 devices, in which the glitch happens even if we try to set just the input gain level without changing the session mode. We are not sure if this is a hardware-related bug in iphone 5, or if it is fixable software glitch in the future version of ios. For the moment we are looking for workaround that can avoid this glitch while automatic gain control and noise canceling are disabled.

This sound was created using audacity. First of all i chose a frequency of 432 hz ( a number which includes the golden rule/proportion), then i created a gradual rise in the first 4 seconds, leading into a peak which descends so it can go up again, creating an effect of confusion. At the end, the sound raises gradually and rapidly to reach its peak once again. This sound recreates, for me, a fast- moving ufo (unidentified flying object) and includes the notion of conspiracy in our society- the changing of the frequency of the tone “la “ from 432 hz to 440 hz in 1953 by the nazis. La règle d’or- 432 hertz. Le ton « la » est une pointe centrale dans le réglage des instruments musicaux. Le ministre de la propagande en allemagne pendant l’époque des nazis a fait un décret général avec lequel il a changé la tonalité « la »de 432 hz en 440 hz. On utilise cette hauteur à partir de 1939 jusqu’à nos jours. Il y a eu des protestes de la part de professeur dussault de la conservatoire parisienne qui a fait une pétition signé par 23 000 artistes françaises mais sans aucun résultat. L’organisation internationale de standardisation(iso) a accepté en 1953 les changements et on utilise la valeur de 440 hz depuis. Des recherches montrent que ce changement a des effets incontournables sur le corps et le cerveau humain- les gens entrent dans un chaos. Ce changement a été caché du monde entier parce que c’est le point de la balance dans la nature. 432 hz est la vibration qui inclue aussi le règle d’or (ou la proportion de dieu). Quand on écoute de la musique en 440 hz la première chose qu’on remarque c’est une fatigue, aucun envie de faire n’importe quoi et beaucoup d’autres ( y inclus le mouvement de notre adn) une étude récent montre que l’utilisation de 440 hz crée des mouvais effets dans la nature et dans toutes les êtres vivantes. Cette article m’a inspirée à recréer un son avec une fréquence de 432 hz qui monte et baisse graduellement. C’est un son seul de type complexe(nodal). Il est de type v( continu varié), il est éclatant,clair et lisse. L’attaque du début est graduelle et violente. Le son varie en « hauteur » de plus fort au moins fort et l’inverse, recréant un effet d’un ovni qui passe à côté de vous.

88 piano keys, long natural reverb: up to 13 seconds per note. This is me giving back. I love freesound. You guys saved my bacon back in the day. Recently i searched for free piano notes for a game i'm making, but the only ones i could find ended too quickly. I need long reverb! luckily i have an old piano, so i made my own. So this is me giving back. This is an old piano!!!. We had the piano tuned a year ago, but it is well over 60 years old, so be warned! these notes have character! if you want perfect tone, either edit them individually, generate something artificially, or buy a professional set. But if you want a piano with personality, this is for you. Being an old piano, it only has 85 keys. So i created the highest 3 notes by speeding up previous notes, to make the modern standard 88 keys. How the notes were created. The notes are created on an old (well over 50 years) steinhoff upright piano. It only has 85 keys, so i faked the highest 3 keys by taking previous keys and changing their pitch. I opened the top, balanced my trusty everesta bm-800 condenser microphone across the top near the high note end, and held down the "loud" pedal. Each note was then hit and kept pressed down until i could no longer hear any reverb. Notes were saved as mp3 using my laptop, using free sound recorder on the highest quality settings. Yeah, i know it isn't flac, but i am strictly amateur with budget to match, and that was the best i could do. After that, all editing was of course uncomopressed until the final save. How the notes were edited. Editing was kept to a minimum, mainly to enhance the reverberation. All editing took place on audacity on linux mint. First i cropped any silence from the start. Next, used the envelope function to gradually increae volume to 200% over a couple of seconds. That is, the quietest part of the reverb is twice as loud as you might expect. Because for my game i sometimes need a single piano key to last ten seconds. Next i maximised the volume. If there was just a single stray waveform that stuck out then i reduced that by 2db or so then maximised again. Because like i said, i want to hear that reverb! i then found the part where background noise starts to be noticeable, and faded out over 1 second or so. This meant that the lowest notes had as much as 13 seconds of reverb, whereas the highest notes might only have 2 or so. Finally i checked the result, and edited three or four notes that i felt were just too ugly (badly tuned, or for some reason the software suddenly got hissy when the note became too quiet. Weird. ) i also slightly changed the pitch of a couple of notes that were slightly out of tune but otherwise ok. No doubt a better ear than mine could teak all of the notes. But as i said, it's an old piano and we're keeping it real. Finally, files were compressed to ogg at the highest quality setting, using soundkonverter. Why not flac?. I live in the countryside with very slow broadband, so i apologise for including more of the original files. But as it was, uploading this zip file took about an hour. Enjoy. Legal. Use this for anything you want, commercial or not, credit me or not. Consider it public domain. My main concern is that i had completely legal sound for my game, with nice long reverb and character. Uploading it here provides proof that i created it first, just in case anybody comes back and says "those are mine" (it happens).
