Per semplificare il processo, abbiamo sviluppato procedure standardizzate e un software dedicato. Questi strumenti innovativi aiutano ricercatori e operatori a creare spettrogrammi dettagliati e analisi visive, consentendo loro di estrarre informazioni critiche in modo rapido ed efficiente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La maggior parte delle procedure seguenti sono per macchine MS Windows, ma stiamo cercando di estendere i pacchetti anche a OSX!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cosa offrono i nostri processi:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Organizzazione impeccabile: dimenticate i file audio disordinati! Le nostre procedure standardizzano la <strong>nomenclatura dei file<\/strong>, garantendo una timeline chiara e facilmente interpretabile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Affidabilit\u00e0 garantita: un <strong>controllo automatico dell&#8217;integrit\u00e0 dei file audio (WAV)<\/strong> assicura che i dati siano privi di errori e pronti per l&#8217;analisi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Spettrogrammi personalizzati: <strong>generate spettrogrammi <\/strong>con una finestra temporale standard di 15 minuti ottimizzata per le vostre esigenze di ricerca. Regolate i parametri di base per una visualizzazione ottimale del segnale.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Panoramica: <strong>crea linee temporali estese<\/strong> (come opzione) per visualizzare periodi di tempo pi\u00f9 lunghi in un&#8217;unica immagine, facilitando l&#8217;identificazione di modelli a lungo termine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Classificazione intuitiva:<strong> classifica visivamente il contenuto<\/strong> degli spettrogrammi per identificare le classi di segnali di interesse. Genera tabelle di dati pronte per la rappresentazione grafica e l&#8217;analisi statistica.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Software di aiuto per classificazione di spettrogrammi\" src=\"https:\/\/player.vimeo.com\/video\/1067235455?h=a58400560c&amp;dnt=1&amp;app_id=122963\" width=\"790\" height=\"444\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture; clipboard-write; encrypted-media\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Ipotesi per la denominazione dei file: verso uno standard condiviso<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Nel campo dell&#8217;acustica subacquea sono state proposte diverse convenzioni per la denominazione dei file, ciascuna con le proprie motivazioni. Dopo un&#8217;attenta valutazione, abbiamo scelto di adottare un formato ampiamente riconosciuto, in linea con quello utilizzato da dispositivi come SoundTrap:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Struttura del nome del file:<\/strong> il nome del file \u00e8 composto da due segmenti separati da un punto (.). Il primo segmento include informazioni identificative quali l&#8217;ID del registratore, la campagna di distribuzione o altri metadati rilevanti. Il secondo segmento riporta la data (AAMMGG) e l&#8217;ora (HHmmss) di inizio della registrazione.<\/li>\n\n\n\n<li><strong>Formato ed estensione:<\/strong> tutti i file sono in formato WAV non compresso, con estensione .WAV.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Esempi di nomi di file conformi:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>lavagna-44D45.241211090655.wav<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>test_33D566.250214153411.wav<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8230;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00c8 possibile trovare facilmente l&#8217;<strong>utilit\u00e0 di rinomina dei file<\/strong> preferita se \u00e8 necessario rinominare un intero batch di file e\/o se le registrazioni non sono ancora conformi a questo standard.

Le librerie Windows di ffmpeg sono <a href=\"https:\/\/www.ffmpeg.org\/download.html#build-windows\">qui<\/a>. Scarica il pacchetto necessario (tre file eseguibili), decomprimilo e metti tutti i file nella stessa cartella in cui si trova SoX <br>(SoX dovrebbe gi\u00e0 essere nel percorso di ricerca del tuo sistema, quindi il computer trover\u00e0 anche i file di ffmpeg quando necessario).<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3.
